Using MVC Grid In MVC

SibeeshVenu — Fri, 11 Dec 2015 00:00:15 +0000

In this post we will see how we can develop a MVC grid in our MVC application. There are so many grids are available in the industries, most of them are useful. Here we are going to use a grid called MVC grid, which uses bootstrap and jQuery. We will create some dynamic data using list first, once it is done, we will send this data to the MVC grid. Sounds good? I hope you will like this article.

Using MVC Grid In MVC

Background

I have been working with the Grid controls for a long long time. So far I have worked with jQX Grid, jQ Grid, jQuery Datatables, Pivot tables, KO grid etc. It is always interesting to work with some controls. I always loved it. recently I worked with MVC grid. So I thought of sharing that experience with you all.

Create a MVC application

First, we will start with creating an MVC application. Open your visual studio, then click File->New->Project. Name your project.

Install MVC Grid

The next step we are going to do is, installing the MVC grid to our project. To install, please right click your solution and click on Manage NuGet packages.

Select NuGet Package

Now you can see a new window, please search for MVC grid in the search box. And then click Install.

Install_MVC_Grid_To_Project

Once you installed, you can see there is a new reference file has been added(GridMVC), you can also notice that two views are created (_Grig.cshtml,_GridPager.cshtml) and one CSS file and some scripts. Now we will move to our next step.

Dependencies

As I said before, MVC grid uses bootstrap for design. So the next thing we need to is to install bootstrap in our project. For that, go to NuGet packages again and search for bootstrap.

Install_Bootstrap_To_Project

You can see some new CSS files and scripts has been added to our project. So the set up has been done. Now what we need to do is to move on the coding part.

Create a controller

Now we can create a new controller, in my case I created a controller ‘HomeController’. In my controller I am going to call a model action which will return some dynamic data. See the code below.

[csharp]
public class HomeController : Controller
{
//
// GET: /Home/

public ActionResult Index()
{
Test t = new Test();
var myList= t.GetData();
return View(myList);
}

}
[/csharp]

As you can see I am creating an instance of my model Test, now we will create our model class. Shall we?

Create Model

I have create a model class with the name Test. Here I am creating some data dynamically using a for loop and assign those values to a list. Please see the codes below.

[csharp]
namespace AsyncActions.Models
{
public class Test
{
public List GetData()
{
try
{
List cst = new List();
for (int i = 0; i < 100; i++)
{
Customer c = new Customer();
c.CustomerID = i;
c.CustomerCode = "CST" + i;
cst.Add(c);
}
return cst;
}
catch (Exception)
{
throw new NotImplementedException();
}

}
}
public class Customer
{
public int CustomerID { get; set; }
public string CustomerCode { get; set; }
}
}
[/csharp]

As you can see I am creating a list of type Customer. Is that fine? Now what is pending? Yes, a view.

Create a strongly typed view

Now we are going to create a strongly typed view.

Create_Strongly_Typed_View

When you create a view as strongly typed view, your view header will be as follows. @model List

So our view is ready, now we can do some codes in our view to populate our grid. Are you ready? First thing is you need to include the needed references to our view, you can do this in the file called Layout.cshtml. Here I am going to add those references directly to the view.

[html]

[/html]

Add the grid namespace

You can add the grid namespace as follows.

[html]
@using GridMvc.Html
[/html]

Next thing is to add grid implementation.

MVC Grid Implementation

To add a MVC grid as our requirement, you need to add the codes as below.

[csharp]
@Html.Grid(Model).Columns(columns =>
{
columns.Add(foo => foo.CustomerID).Titled("Customer ID").SetWidth(50).Sortable(true).Filterable(true);
columns.Add(foo => foo.CustomerCode).Titled("Customer Code").SetWidth(50).Sortable(true).Filterable(true);
}).WithPaging(20)

[/csharp]

As you can see we are using the columns Customer.CustomerID and Customer.CustomerCode.

Output

MVC_Grid_With_Dynamic_Data

Add more Grid features

To set the paging we can use the option WithPaging(20).
To add title we can use Titled property.
To set width we can use SetWidth property.
To set sort we can use Sortable property.
To set filter we can use Filterable property.

You can always see the additional options here .

Conclusion

Did I miss anything that you may think which is needed? Could you find this post as useful? I hope you liked this article. Please share me your valuable suggestions and feedback.

Your turn. What do you think?

A blog isn’t a blog without comments, but do try to stay on topic. If you have a question unrelated to this post, you’re better off posting it on C# Corner, Code Project, Stack Overflow, Asp.Net Forum instead of commenting here. Tweet or email me a link to your question there and I’ll definitely try to help if I can.

Change Themes Dynamically In Grid

SibeeshVenu — Wed, 28 Oct 2015 13:40:51 +0000

In this post we will see how we can Change Themes Dynamically In Grid . I recently came across a situation to change the grid’s theme dynamically, when ever user select any theme. So I have done this requirement by using some in-built functionalities of jQWidget JQX grid. Here I am going to share you that. I hope you will like it.

To load a grid from a JSON, you can follows the steps as discussed in this article: Load jQWidget JQX Grid From JSON

Background

If you are new to JQWidget JQX Grid, Please find out here: http://sibeeshpassion.com/category/jqwidgets/

Download the Source Code

Please download the source code from here: Change Themes Dynamically

Using the code

I hope you have implemented your grid as shown in that article. Now I guess your page will be looking like this.

[html]

[/html]

Now let us make sure that grid is working fine. Please run your project.

Change Themes Dynamically In Grid

Cool, so grid is loaded. Now need to add a select control in which we are going to load theme names so that user can select the theme and apply. Is that fine?

[html]

[/html]

The next thing is we need to add the CSS links to the page, here I am going to add some of the CSS references as follows.

[html]

[/html]

Have you noticed that we are calling the function applyNewCSS in the on change event of the select control. So next thins we will add that function.

[js]
function applyNewCSS() {
var css = $.trim($("#selectOptions").val());
if (css == ‘metro’) {
$("#jqxgrid").jqxGrid({ theme: ‘metro’ });
}
else if (css == ‘metrodark’) {
$("#jqxgrid").jqxGrid({ theme: ‘metrodark’ });
}
else if (css == ‘office’) {
$("#jqxgrid").jqxGrid({ theme: ‘office’ });
} else if (css == ‘orange’) {
$("#jqxgrid").jqxGrid({ theme: ‘orange’ });
} else if (css == ‘energyblue’) {
$("#jqxgrid").jqxGrid({ theme: ‘energyblue’ });
} else if (css == ‘darkblue’) {
$("#jqxgrid").jqxGrid({ theme: ‘darkblue’ });
} else if (css == ‘black’) {
$("#jqxgrid").jqxGrid({ theme: ‘black’ });
} else if (css == ‘shinyblack’) {
$("#jqxgrid").jqxGrid({ theme: ‘shinyblack’ });
} else if (css == ‘lightness’) {
$("#jqxgrid").jqxGrid({ theme: ‘lightness’ });
} else if (css == ‘ui-le-frog’) {
$("#jqxgrid").jqxGrid({ theme: ‘ui-le-frog’ });
} else if (css == ‘ui-darkness’) {
$("#jqxgrid").jqxGrid({ theme: ‘ui-darkness’ });
} else if (css == ‘ui-sunny’) {
$("#jqxgrid").jqxGrid({ theme: ‘ui-sunny’ });
}
else if (css == ‘android’) {
$("#jqxgrid").jqxGrid({ theme: ‘android’ });
}
}
[/js]

So we can add the theme to the grid as $(“#jqxgrid”).jqxGrid({ theme: ‘theme name’ });

Here we are applying the theme to the grid according to the user selection. Oops, we forgot one thing. If you apply CSS style sheet directly, the styles won’t get applied in the page contents. For that we need to disable the remaining style sheets and enable the selected one alone.

Following code will do that magic.

[js]
var i, link_tag;
for (i = 0, link_tag = document.getElementsByTagName("link") ; i < link_tag.length; i++) {
if ((link_tag[i].rel.indexOf("stylesheet") != -1) && link_tag[i].title) {
link_tag[i].disabled = true;
if (link_tag[i].title == css) {
link_tag[i].disabled = false;
}
}
set_cookie(‘style’, css, 30);
}
[/js]

We are finding all of the link reference and find out whose rel property has the word ‘stylesheet’. Now it is time to see how it woks.

Change Themes Dynamically In Grid

You can see that the grid themes are changing according to the user selection of theme.That’s all we have done it.

Change Header Names Dynamically In JQwidgets JQX grid

SibeeshVenu — Wed, 28 Oct 2015 11:15:33 +0000

In this post we will see how we can Change Header Names Dynamically In JQwidgets JQX grid. I recently came across a situation to change the grid’s header columns text should be changed dynamically, when ever user change a text box content. So I have done this requirement by using some in-built functionalities of jQWidget JQX grid. Here I am going to share you that. I hope you will like it.

Now let us make sure that grid is working fine. Please run your project.

Change Header Names Dynamically In JQwidgets JQX grid

Cool, so grid is loaded. Now need to add a select control in which we are going to load the grid header names so that user can select which one’s header must be changed, and a text box where a user can enter the text to be changed for the selected header. Is that fine?

[html]

[/html]

The next thing is we need to add the options to the select control. Right? We can get the column properties of JQX grid as $(“#jqxgrid”).jqxGrid(‘columns’).records. Now we will create a ready function in the grid settings and append the values. Following is the code for that.

[js]
ready: function () {
var options = "";
var headerNames = $("#jqxgrid").jqxGrid(‘columns’).records;
for (var i = 0; i < headerNames.length; i++) {
options += "";
}
$("#selectOptions").html(options);
}
[/js]

What is next? Yeah, we need to fire the text box change event.

[js]
$("#changeName").change(function (e) {
$("#jqxgrid").jqxGrid(‘setcolumnproperty’, $(‘#selectOptions option:selected’).val(), ‘text’, $(‘#changeName’).val());
});
[/js]

In the text box change event we have written the code to change the header column text property.

Here we are using setcolumnproperty method which already available in the JQWidget library.

Now it is time to see how it woks.

You can see that the header column text has been changed from ‘Area Code’ to ‘New Area Code’.That’s all we have done it.

Order Filter Conditions In jQWidget JQX Grid

SibeeshVenu — Tue, 20 Oct 2015 09:56:57 +0000

In this post we will see how we can set the default filter condition in JQX Grid filter drop down or how we can order jqx grid jqwidget filter conditions. I recently came across a situation that the grid filter condition must be shown as ‘equal’ for any type of filter like string, numeric. So I have done this requirement by using some in-built functionalities of jQWidget JQX grid. Here I am going to share you that. I hope you will like it.

To load a grid from a JSON, you can follows the steps as discussed in this article: Load jQWidget JQX Grid From JSON

Now let us make sure that grid is working fine. Please run your project.

Order Filter Conditions In jQWidget JQX Grid

Cool, so grid is loaded. Now have you noticed that the filter condition shows by default is ‘Contains’ ? Now we are going to change that. You might be thinking what kind of requirement is this. But trust me. If client ask, we must do anything at any cost.

Now we are going to add three functions to the grid settings.

rendered

updatefilterconditions

updatefilterpanel

So our grid settings will be looking as follows.

[js]
$("#jqxgrid").jqxGrid(
{
source: data,
columns: [{ "text": "Area Code", "dataField": "AreaCode", "cellsalign": "left", "cellsformat": "d" }, { "text": "Revenue", "dataField": "Revenue", "cellsalign": "right", "cellsformat": "c2" }],
pageable: true,
filterable: true,
sortable: true,
rendered: function () {
var localizationobj = {};
filterstringcomparisonoperators = [‘equal’, ’empty’, ‘not empty’, ‘contains’, ‘does not contain’, ‘starts with’, ‘ends with’, ‘null’];
filternumericcomparisonoperators = [‘equal’, ‘not equal’, ‘less than’, ‘less than or equal’, ‘greater than’, ‘greater than or equal’, ‘null’, ‘not null’];
filterdatecomparisonoperators = [‘equal’, ‘not equal’, ‘less than’, ‘less than or equal’, ‘greater than’, ‘greater than or equal’, ‘null’, ‘not null’];
filterbooleancomparisonoperators = [‘equal’, ‘not equal’];

localizationobj.filterstringcomparisonoperators = filterstringcomparisonoperators;
localizationobj.filternumericcomparisonoperators = filternumericcomparisonoperators;
localizationobj.filterdatecomparisonoperators = filterdatecomparisonoperators;
localizationobj.filterbooleancomparisonoperators = filterbooleancomparisonoperators;

// apply localization.
$("#jqxgrid").jqxGrid(‘localizestrings’, localizationobj);
},
updatefilterconditions: function (type, defaultconditions) {
var stringcomparisonoperators = [‘EQUAL’, ‘EMPTY’, ‘NOT_EMPTY’, ‘CONTAINS’, ‘DOES_NOT_CONTAIN’, ‘STARTS_WITH’, ‘ENDS_WITH’, ‘NULL’];
var numericcomparisonoperators = [‘EQUAL’, ‘NOT_EQUAL’, ‘LESS_THAN’, ‘LESS_THAN_OR_EQUAL’, ‘GREATER_THAN’, ‘GREATER_THAN_OR_EQUAL’, ‘NULL’, ‘NOT_NULL’];
var datecomparisonoperators = [‘EQUAL’, ‘NOT_EQUAL’, ‘LESS_THAN’, ‘LESS_THAN_OR_EQUAL’, ‘GREATER_THAN’, ‘GREATER_THAN_OR_EQUAL’, ‘NULL’, ‘NOT_NULL’];
var booleancomparisonoperators = [‘EQUAL’, ‘NOT_EQUAL’];
switch (type) {
case ‘stringfilter’:
return stringcomparisonoperators;
case ‘numericfilter’:
return numericcomparisonoperators;
case ‘datefilter’:
return datecomparisonoperators;
case ‘booleanfilter’:
return booleancomparisonoperators;
}
},
updatefilterpanel: function (filtertypedropdown1, filtertypedropdown2, filteroperatordropdown, filterinputfield1, filterinputfield2, filterbutton, clearbutton,
columnfilter, filtertype, filterconditions) {
var index1 = 0;
var index2 = 0;
filtertypedropdown1.jqxDropDownList({ autoDropDownHeight: true, selectedIndex: index1 });
filtertypedropdown2.jqxDropDownList({ autoDropDownHeight: true, selectedIndex: index2 });
}
});
});
[/js]

Here in the updatefilterpanel we are setting the index for the filter drop down. And in updatefilterconditions and rendered functions we are applying the localization according to our requirement. Now save the changes and run your grid again, you can see the filter option ‘equal’ will be loaded as default.

Order Filter Conditions In jQWidget JQX Grid

That’s all we have done this requirement of ordering the jQWidget JQX grid filter conditions.

Custom Events In Highcharts

SibeeshVenu — Tue, 06 Oct 2015 13:38:03 +0000

In this post we will discuss how we can handle custom events in HighChart . HighChart has already given enough events but sometimes we may need to handle some additional events. For example if we need to fire an alert if user double clicks on the points. Here I am using HighChart Drill Down Chart, So As you all know drill down chart is a chart which populate another chart according to the user action, ie if user click on a particular series, a chart with the related data of the clicked series will get loaded. Now we will go and see it in action. I hope you will like this.

Background

I am working in a BI dashboard application, thus recently I got a requirement of giving an alert if user clicks on the chart point. Here I will explain the same with an example of high chart drill down type.

Please see the demo here: Custom Events in Drill Down Chart

Using the code

First of all we will create a page as follows.

[html]

Fire Double Click Events In Highcharts

Fire Double Click Events In Highcharts – Sibeesh Passion (Sibeesh Passion )

[/html]

Next we will add the needed references.

[js]

[/js]

Here you can see we have added a file customEvents.js, please do not forget to add this file. This is much important.

The next step is to load the chart, We can create a chart as follows.

[js]

[/js]

Now if you run your page you can see a drill down chart as follows.

Fire Double Click Events In Highcharts

Now here is the main part, we need to add a plot option to the chart option so that we can track the events. Please add the preceding lines of code.

[js]
plotOptions: {
series: {
point: {
events: {
dblclick: function () {
setTimeout(function () {
alert(‘Double Click Is Not Permitted’);
}, 1000);
return false;
}
}
}
}
}
[/js]

We have created a custom double click event dblclick successfully. In this way you can create custom events in highchart wherever you want, like create click and double click event in axis and label and data labels so on…

That’s all, we did it. Now please find the complete code.

Complete Code

[html]

Fire Double Click Events In Highcharts

Using Spire.PDF In Asp.Net

SibeeshVenu — Mon, 24 Aug 2015 16:41:58 +0000

In this article we are going to see a new product Spire.PDF which helps us to create, manipulate PDF and many more. This product has been introduced by the company E-Iceblue. The company has introduced so many products like this. For example Spire.Doc, Spire.XLS. I hope you have read my articles under these categories. If you have not read them, I suggest you to rad here.

Using Spire.Doc

Using Spire.Xls

Working With Charts Using Spire.Xls

Download source code

Using Spire PDF

Background

As you all know a PDF is a most accurate and effective format of a document. A document is very important in our life, so we create PDF files. Now coming to the matter, As we all are developers, we develops anything that is needed. But have you ever tried creating and managing PDF file? Awww!. That’s a quite difficult task right? Still it is possible. “Everything is possible, the word impossible itself says I am possible”. Now It is time to introduce you a product which let you do these task in an easy manner. So that means, you are able to do these task with a little effort.

Create a new Project

Now we will create a new Project in our Visual studio.

Using_Spire_PDF_Create_New_Project

Add License Information To Project

I am using evaluation version with one month temporary license. There are free versions also available for spire.pdf with some limitation. You can try that.

Using_Spire_PDF_Add_License_To_Project

Download the files

You can always the needed files from here: Download Spire.PDF

Install Spire.PDF

Now click on the exe file after you extract the downloaded file. The installation will get started then.

Using_Spire_PDF_Installing

Using_Spire_PDF_Installing_Complete

So Shall we start?

Once you Installed, you are ready to go. We will start with a “Simple Web Application” . I hope you have a created a new web application and added your license as suggested before. Now create a page.

So your page will be looking as follows.

[html]
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="UsingSpirePDF.Default" %>

[/html]

Now right click on your project and click add reference, in the browse tab find out the folder in which you have installed spire.pdf. Usually it will be in the C:\Program Files\e-iceblue\Spire.pdf. Now just find your framework version from BIN folder and add Spire.pdf.dll

Using_Spire_PDF_Adding_Reference

Now we have added reference too. So shall we start coding ?

Using the code

There are so many features available, we will look in to most useful features which you might found useful.

Convert PDF Page to Image

In this part, we will see how can we convert a PDF file to image with a specific resolution. It is so simple and powerful.

We will create a button as follows.

[html]

[/html]

Next we need to add the needed references.

[csharp]
using Spire.Pdf;
using Spire.Pdf.Graphics;
using System;
using System.Drawing;
[/csharp]

And in the button click we can write the preceding codes.

[csharp]
protected void btnConvertToImage_Click(object sender, EventArgs e)
{
try
{
PdfDocument documemt = new PdfDocument();
documemt.LoadFromFile(@"D:\\sibeeshpassion.pdf");
Image image = documemt.SaveAsImage(0, PdfImageType.Bitmap, 400, 400);
image.Save(@"D:\\result.jpg");
documemt.Close();
}
catch (Exception)
{

throw;
}
}
[/csharp]

As you can see we are calling the below function to generate the image.

[csharp]
documemt.SaveAsImage(0, PdfImageType.Bitmap, 400, 400);
[/csharp]

And this function has overloaded as in the below image.

Using_Spire_PDF_Covert_PDF_To_Image

Here we are taking the pdf file sibeeshpassion.pdf and we are getting a image as follows as output.

Using_Spire_PDF_Covert_PDF_To_Image_Output

Cool Right?

Now we will see another implementation.

Security

There are few many security options are also available with this package like Encryption and Decryption of the pdf file and creating a digital signature and many more.

Encrypting PDF File

In this step, we are going to set a password for our pdf document.

To work with security, you need to add a new reference as follows.

[csharp]
using Spire.Pdf.Security;
[/csharp]

Now add a new button as follows.

[html]

[/html]

Now it is time for click event.

[csharp]
protected void btnEncryptPDF_Click(object sender, EventArgs e)
{
try
{
PdfDocument doc = new PdfDocument(@"D:\\sibeeshpassion.pdf", "sibeeshpassionEncrypted");
doc.Security.KeySize = PdfEncryptionKeySize.Key256Bit;
doc.Security.OwnerPassword = "sibeeshpassion";
doc.Security.UserPassword = "sibeesh";
doc.Security.Permissions = PdfPermissionsFlags.Print | PdfPermissionsFlags.CopyContent;
}
catch (Exception)
{

throw;
}
}
[/csharp]

Three kind of pdf key size are available as shown in the below image.

Using_Spire_PDF_Possible_Key

And as you can see, we are setting some permission by using the preceding code.

[csharp]
doc.Security.Permissions = PdfPermissionsFlags.Print | PdfPermissionsFlags.CopyContent;
[/csharp]

There are some other permission options also available.

Using_Spire_PDF_Possible_File_Permissions

Now if you try to open our pdf again, it will ask you for a password which we have set in the above codes. Cool.

Decryption of PDF File

AS we encrypt our pdf file, we need to do decryption also right?

Add an another button.

[html]

[/html]

Add the following code block in the button click event.

[csharp]
try
{
PdfDocument doc = new PdfDocument(@"D:\\sibeeshpassion.pdf", "sibeeshpassionEncrypted");
//extract image
Image image = doc.Pages[0].ImagesInfo[0].Image;
doc.Close();
//Save image file.
image.Save("sibeeshpassionDecrypted.png", System.Drawing.Imaging.ImageFormat.Png);
//Launching the image file.
System.Diagnostics.Process.Start("sibeeshpassionDecrypted.png");

}
catch (Exception ex)
{

throw;
}
[/csharp]

Once you run the above codes, your pdf file will be decrypted.

Watermark

You can add watermark to your pdf file easily with this package.

Adding a watermark

There are two kind of watermarks. One is text watermark and other is image watermark.

Now we will add another button.

[html]

[/html]

And in the button click we can write the preceding codes.

[csharp]
protected void btnAddImageWatermark_Click(object sender, EventArgs e)
{
try
{
PdfDocument doc = new PdfDocument("D:\\Sibi.pdf", "Sibi");
Image img = Image.FromFile("D:\\sibi.jpg");
doc.Pages[0].BackgroundImage = img;
doc.SaveToFile("D:\\Sibeesh.pdf");
doc.Close();

}
catch (Exception)
{

throw;
}
}
[/csharp]

As you can see we are taking a pdf file and add a watermark image to the file and at last we save it to an another file. In this case from sibi.pdf to sibeesh.pdf.

I am taking sibi.jpg as the water mark image, so you can see the pdf file with watermarked image as follows.

Using_Spire_PDF_Adding_Watermark

Please be noted that, you can convert your PDF file to any other file format, there are plenty of options available. Please try that too. I have given only few options which I use always.

Conclusion

These are the features I loved using Spire.PDF. It is much effective and simple. What do you think about this? Are you using Spire.PDF yet? Do you plan to try this?Did I miss anything that you may think which is needed?. I hope you liked this article. Please share me your valuable suggestions and feedback.

Your turn. What do you think?

A blog isn’t a blog without comments, but do try to stay on topic. If you have a question unrelated to this post, you’re better off posting it on Stack Overflow instead of commenting here. Tweet or email me a link to your question there and I’ll definitely try to help if I am able to.

Working With Charts Using Spire.XLS

SibeeshVenu — Tue, 11 Aug 2015 15:45:19 +0000

Today we are going to see an another series of new product Spire.XLS which helps us to create, manipulate, convert EXCEL file to other formats, create charts dynamically and many more. This product has been introduced by the company E-Iceblue. I hope you have read my article of Spire.Doc and Spire.XLS. If you have not read it, I recommend you to read it here: Using Spire.XLS

Background

As you all know, charts are the graphical representations of our data. It is much easier to understand our data if it is in a graphical form. Am I right? It is easy to create a static chart, but what about a dynamic one? It will be bit tough right? But by using Spire.XLS, we can create any kind of charts easily. In this post, we will see those implementations.

Download the files

You can always get the needed files from here: Download Spire.XLS

Install Spire.XLS

I am using evaluation version with one month temporary license. There are free versions also available for spire.xls with some limitation. You can try that. Now click on the exe file after you extract the downloaded file. The installation will get started then.

Using the code

Before starting with coding you need to add the needed namespaces as follows.

[csharp]
using Spire.Xls;
using System.Drawing;
[/csharp]

First of all create a form and then a button, in the button click add the following lines of codes.

C# Code

[csharp]
private void button1_Click(object sender, EventArgs e)
{
try
{
//Create a new workbook
Workbook workbook = new Workbook();
//Initialize worksheet
workbook.CreateEmptySheets(1);

chart.SeriesDataFromRange = false;
//Set position of chart
chart.LeftColumn = 1;
chart.TopRow = 6;
chart.RightColumn = 9;

chart.ChartTitleArea.IsBold = true;
chart.ChartTitleArea.Size = 12;
//Initialize the chart series
Spire.Xls.Charts.ChartSerie cs = chart.Series[0];
//Chart Labels resource
cs.CategoryLabels = sheet.Range["A2:A5"];
//Chart value resource
cs.Values = sheet.Range["B2:B5"];
//Set the value visible in the chart
cs.DataPoints.DefaultDataPoint.DataLabels.HasValue = true;
//Year
sheet.Range["A1"].Value = "Year";
sheet.Range["A2"].Value = "2002";
sheet.Range["A3"].Value = "2003";
sheet.Range["A4"].Value = "2004";
sheet.Range["A5"].Value = "2005";
//Sales

sheet.Range["B2"].NumberValue = 4000;
sheet.Range["B3"].NumberValue = 6000;
sheet.Range["B4"].NumberValue = 7000;
sheet.Range["B5"].NumberValue = 8500;

sheet.Range["A1:B5"].Style.Borders[BordersLineType.EdgeRight].LineStyle = LineStyleType.Thin;
//Number format
sheet.Range["B2:C5"].Style.NumberFormat = "\"$\"#,##0";
chart.PlotArea.Fill.Visible = false;
//Save the file

}
catch (Exception)

In the above lines code, we are creating a pie chart by giving some settings and data and load it. Now if you run you will get an output as follows.

In the above mentioned lines of codes, we are doing so many processes, those processes are listed below.

Creating a new workbook

Initialize worksheet newly created

Set sheet name of worksheet

Set the grid lines invisible

Creating a chart

Set region of chart data

Set position of chart

Set Chart title

Initialize the chart series

Setting Chart Labels resource

Setting Chart value resource

Set the value visible in the chart

Apply Styles

Apply Borders

Give Number format if necessary

Save the file

At last Launch the file

Wow!. That’s cool right?

Not yet finished!. There are so many things you can try with your sheet object. I suggest you to try those. You will get surprised.

Working With Charts Using Spire XLS Sheet Object

If you want you can set different chart types too, it will give you a great design in your chart. The most useful chart types which I uses is Bar3DClustered, 3DBubble, Bubble, Column3D and many more.

Working_With_Charts_Using_Spire_XLS_Chart_Object

This product gives you many ways to make your chart in the way you like. There are plenty of options available to so so like you can set the Legend Position by using LegendPositionType property.

Next we will see how we can implement Column chart, what ever we have discusses will be same for every charts, but it may have some different properties which is strictly depends on the chart type.

Column Chart

Now we will create an another button and name it Column Chart. And in the button click you need to add the following codes.

C# Code

[csharp]
private void button2_Click(object sender, EventArgs e)
{
try
{
//Load Workbook
Workbook workbook = new Workbook();
workbook.LoadFromFile(@"D:\Sample.xlsx");
Worksheet sheet = workbook.Worksheets[0];
//Add Chart and Set Chart Data Range
Chart chart = sheet.Charts.Add(ExcelChartType.ColumnClustered);
chart.DataRange = sheet.Range["D1:E17"];
chart.SeriesDataFromRange = false;
//Chart Position
chart.LeftColumn = 1;
chart.TopRow = 19;
chart.RightColumn = 8;
chart.BottomRow = 33;
//Chart Border
chart.ChartArea.Border.Weight = ChartLineWeightType.Medium;
chart.ChartArea.Border.Color = Color.SandyBrown;
//Chart Title
chart.ChartTitle = "Parts Sales Info";
chart.ChartTitleArea.Font.FontName = "Calibri";
chart.ChartTitleArea.Font.Size = 13;
chart.ChartTitleArea.Font.IsBold = true;
//Chart Axes
chart.PrimaryCategoryAxis.Title = "Parts";
chart.PrimaryCategoryAxis.Font.Color = Color.Blue;
chart.PrimaryValueAxis.Title = "Amounts";
chart.PrimaryValueAxis.HasMajorGridLines = false;
chart.PrimaryValueAxis.MaxValue = 350;
chart.PrimaryValueAxis.TitleArea.TextRotationAngle = 90;
//Chart Legend
chart.Legend.Position = LegendPositionType.Right;
//Save and Launch
workbook.SaveToFile("ExcelColumnChart.xlsx", ExcelVersion.Version2010);
System.Diagnostics.Process.Start("ExcelColumnChart.xlsx");

}
catch (Exception)
{

throw;
}
}
[/csharp]

VB.NET Code

[vb]
‘Load Workbook
Dim workbook As New Workbook()
workbook.LoadFromFile("E:\Sample.xlsx")
Dim sheet As Worksheet = workbook.Worksheets(0)
‘Add Chart and Set Chart Data Range
Dim chart As Chart = sheet.Charts.Add(ExcelChartType.ColumnClustered)
chart.DataRange = sheet.Range("D1:E17")
chart.SeriesDataFromRange = False
‘Chart Position
chart.LeftColumn = 1
chart.TopRow = 19
chart.RightColumn = 8
chart.BottomRow = 33
‘Chart Border
chart.ChartArea.Border.Weight = ChartLineWeightType.Medium
chart.ChartArea.Border.Color = Color.SandyBrown
‘Chart Title
chart.ChartTitle = "Parts Sales Info"
chart.ChartTitleArea.Font.FontName = "Calibri"
chart.ChartTitleArea.Font.Size = 13
chart.ChartTitleArea.Font.IsBold = True
‘Chart Axes
chart.PrimaryCategoryAxis.Title = "Parts"
chart.PrimaryCategoryAxis.Font.Color = Color.Blue
chart.PrimaryValueAxis.Title = "Amounts"
chart.PrimaryValueAxis.HasMajorGridLines = False
chart.PrimaryValueAxis.MaxValue = 350
chart.PrimaryValueAxis.TitleArea.TextRotationAngle = 90
‘Chart Legend
chart.Legend.Position = LegendPositionType.Right
‘Save and Launch
workbook.SaveToFile("ExcelColumnChart.xlsx", ExcelVersion.Version2010)
System.Diagnostics.Process.Start("ExcelColumnChart.xlsx")

[/vb]

Now if you run the code, you can see an output as follows.

Excel Bar Chart

Before going through you must add an new namespace as follows.

[csharp]
using Spire.Xls.Charts;
[/csharp]
Now we will create an another button in our form and in the click event we will write the receding lines of codes.

[csharp]
private void button1_Click(object sender, EventArgs e)
{
try
{
Workbook workbook = new Workbook();
//Initailize worksheet
workbook.CreateEmptySheets(1);
Worksheet sheet = workbook.Worksheets[0];
sheet.Name = "Chart data";
sheet.GridLinesVisible = false;
//Writes chart data
CreateChartData(sheet);
//Add a new chart worsheet to workbook
Chart chart = sheet.Charts.Add();
//Set region of chart data
chart.DataRange = sheet.Range["A1:C5"];
chart.SeriesDataFromRange = false;
//Set position of chart
chart.LeftColumn = 1;
chart.TopRow = 6;
chart.RightColumn = 11;
chart.BottomRow = 29;
chart.ChartType = ExcelChartType.Bar3DClustered;
//Chart title
chart.ChartTitle = "Sales market by country";
chart.ChartTitleArea.IsBold = true;
chart.ChartTitleArea.Size = 12;
chart.PrimaryCategoryAxis.Title = "Country";
chart.PrimaryCategoryAxis.Font.IsBold = true;
chart.PrimaryCategoryAxis.TitleArea.IsBold = true;
chart.PrimaryCategoryAxis.TitleArea.TextRotationAngle = 90;
chart.PrimaryValueAxis.Title = "Sales(in Dollars)";
chart.PrimaryValueAxis.HasMajorGridLines = false;
chart.PrimaryValueAxis.MinValue = 1000;
chart.PrimaryValueAxis.TitleArea.IsBold = true;
foreach (ChartSerie cs in chart.Series)
{
cs.Format.Options.IsVaryColor = true;
cs.DataPoints.DefaultDataPoint.DataLabels.HasValue = true;
}
chart.Legend.Position = LegendPositionType.Top;
workbook.SaveToFile("Sample.xls");
ExcelDocViewer(workbook.FileName);

}
catch (Exception)
{
throw;
}
}
[/csharp]

As you can see we are calling a function CreateChartData to generate the data, so now we will write the function body.

[csharp]
private void CreateChartData(Worksheet sheet)
{
//Country
sheet.Range["A1"].Value = "Country";
sheet.Range["A2"].Value = "Cuba";
sheet.Range["A3"].Value = "Mexico";
sheet.Range["A4"].Value = "France";
sheet.Range["A5"].Value = "German";
//Jun
sheet.Range["B1"].Value = "Jun";
sheet.Range["B2"].NumberValue = 6000;
sheet.Range["B3"].NumberValue = 8000;
sheet.Range["B4"].NumberValue = 9000;
sheet.Range["B5"].NumberValue = 8500;
//Jun
sheet.Range["C1"].Value = "Aug";
sheet.Range["C2"].NumberValue = 3000;
sheet.Range["C3"].NumberValue = 2000;
sheet.Range["C4"].NumberValue = 2300;
sheet.Range["C5"].NumberValue = 4200;
//Style
sheet.Range["A1:C1"].Style.Font.IsBold = true;
sheet.Range["A2:C2"].Style.KnownColor = ExcelColors.LightYellow;
sheet.Range["A3:C3"].Style.KnownColor = ExcelColors.LightGreen1;
sheet.Range["A4:C4"].Style.KnownColor = ExcelColors.LightOrange;
sheet.Range["A5:C5"].Style.KnownColor = ExcelColors.LightTurquoise;
//Border
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeTop].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeTop].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeBottom].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeBottom].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeLeft].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeLeft].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeRight].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeRight].LineStyle = LineStyleType.Thin;
sheet.Range["B2:C5"].Style.NumberFormat = "\"$\"#,##0";
}
[/csharp]

And we will use the preceding function for viewing our chart created.

[csharp]
private void ExcelDocViewer(string fileName)
{
try
{
System.Diagnostics.Process.Start(fileName);
}
catch { }
}
[/csharp]

Now it is time to run our program. You will see the output as follows.

Excel Bar Chart

As you can see it is very easy to give styles and border to our chart.

[csharp]
//Style
sheet.Range["A1:C1"].Style.Font.IsBold = true;
sheet.Range["A2:C2"].Style.KnownColor = ExcelColors.LightYellow;
sheet.Range["A3:C3"].Style.KnownColor = ExcelColors.LightGreen1;
sheet.Range["A4:C4"].Style.KnownColor = ExcelColors.LightOrange;
sheet.Range["A5:C5"].Style.KnownColor = ExcelColors.LightTurquoise;
//Border
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeTop].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeTop].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeBottom].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeBottom].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeLeft].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeLeft].LineStyle = LineStyleType.Thin;
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeRight].Color = Color.FromArgb(0, 0, 128);
sheet.Range["A1:C5"].Style.Borders[BordersLineType.EdgeRight].LineStyle = LineStyleType.Thin;
sheet.Range["B2:C5"].Style.NumberFormat = "\"$\"#,##0";
[/csharp]

Like this we can crate Line Chart, Radar Chart and many more. Please try those too. Now we will see How to Save Excel Charts as Images.

How to Save Excel Charts as Images

Create another button and write the preceding codes in button click.

[csharp]
private void button2_Click(object sender, EventArgs e)
{
Workbook workbook = new Workbook();
workbook.LoadFromFile("D:\\Sample.xlsx", ExcelVersion.Version2010);
Worksheet sheet = workbook.Worksheets[0];
Image[] imgs = workbook.SaveChartAsImage(sheet);
for (int i = 0; i < imgs.Length; i++)
{
imgs[i].Save(string.Format("img-{0}.png", i), System.Drawing.Imaging.ImageFormat.Png);
}

}
[/csharp]

Here we are taking a file called Sample.xlsx and loop through the charts inside the file and save those as images with few lines codes. Sounds good right?

VB.Net Code
[vb]
Dim workbook As New Workbook()
workbook.LoadFromFile("D:\\Sample.xlsx", ExcelVersion.Version2010)
Dim sheet As Worksheet = workbook.Worksheets(0)
Dim imgs As Image() = workbook.SaveChartAsImage(sheet)
For i As Integer = 0 To imgs.Length – 1
imgs(i).Save(String.Format("img-{0}.png", i), ImageFormat.Png)
Next
[/vb]

How To Save the Zoom View of Our Map

SibeeshVenu — Wed, 29 Apr 2015 20:47:44 +0000

Today we will learn how to save the zoom level of our map in our application. By this you can retain the zoomed view that the user sets so that it would be easier for users to identify things in our application.

Background

A few weeks ago I got the requirement to save the zoom level of the map. If you are new to the Bubble Map, please see here: Working with Bubble Map

Download Source Code

Save Zoomed View Of Map

Using the code

I hope you have configured a Bubble Map in your application now. Now it is time to complete our new requirement. Now what we will do is to introduce a new function that retains the zoom level from the session storage and applies it to the map. You must call this function at the end of the map configuration.

The following is the function code.
[js]
var curMax = ”
var curMin = ”
var curMaxY = ”;
var curMinY = ”;
function updateZoom(chart) {
if (sessionStorage.getItem("curMaxZoomMap") != null && typeof sessionStorage.getItem("curMaxZoomMap") != ‘undefined’ && sessionStorage.getItem("curMinZoomMap") != null && typeof sessionStorage.getItem("curMinZoomMap") != ‘undefined’) {
chart.xAxis[0].setExtremes(parseInt(sessionStorage.getItem("curMinZoomMap")), parseInt(sessionStorage.getItem("curMaxZoomMap")));
}
if (sessionStorage.getItem("curMaxZoomMapY") != null && typeof sessionStorage.getItem("curMaxZoomMapY") != ‘undefined’ && sessionStorage.getItem("curMinZoomMapY") != null && typeof sessionStorage.getItem("curMinZoomMapY") != ‘undefined’) {
chart.yAxis[0].setExtremes(parseInt(sessionStorage.getItem("curMinZoomMapY")), parseInt(sessionStorage.getItem("curMaxZoomMapY")));
}
}
[/js]

Now we have seen how to apply the zoom level to the map. Next is how to set the value to the session storage. The fact is that whenever the user does zooming in the map, it fires events in xAxis and yAxis. So we need to crate that events in both axis.

Let’s look at that code now.

[js]
xAxis: {
events: {
afterSetExtremes: function (e) {
curMax = e.max;
curMin = e.min;
sessionStorage.setItem("curMaxZoomMap", curMax);
sessionStorage.setItem("curMinZoomMap", curMin);
}
}
},
yAxis: {
events: {
afterSetExtremes: function (e) {
curMaxY = e.max;
curMinY = e.min;
sessionStorage.setItem("curMaxZoomMapY", curMaxY);
sessionStorage.setItem("curMinZoomMapY", curMinY);
}
}
}
[/js]

Once you have included this event you can see the values in session storage in your browser whenever the user zooms the map.

Save Zoomed View Of Bubble Map

Our next step is to include the zoomTo even in the series of our map.
[js]
events: {
click: function (e) {
e.point.zoomTo();
}
}
[/js]

So your series configuration will be as follows.
[js]
series: [{
mapData: map,
borderColor: ‘#E0E0E0’,
colour: ‘#E0E0E0’,
showInLegend: false,
enableMouseTracking: true,
cursor: ‘pointer’,
dataLabels: {
enabled: true,
format: ‘{point.properties.postal-code}’,
textDecoration: ‘none’,
style: { "color": "darkgrey", "fontWeight": "bold", "HcTextStroke": "0px rgba(0,0,0,0.5)" }
},
events: {
click: function (e) {
e.point.zoomTo();
}
},
}
[/js]

That is all guys, you can retain the zoom level of your map even if you reload. Cool!

Drag and Drop the Legend and Maintain the Position in Chart

SibeeshVenu — Wed, 29 Apr 2015 20:40:08 +0000

Today we will learn how to create a drag-able legend and maintain that position in the chart area, so that once we drag and drop the legend, even if we reload the chart again, it will take the legend position from the session storage, where we have set the values when dropping the legend. Cool, right?

Background

For the past few weeks I have been working in Charts, so a few days ago I got a requirement to make a drag-able legend and maintain the position. As you all know, everyone expects the best from their products, so I began working to satisfy my client by giving them all the feasible options in the chart. Once I was done with that it was good.

Download Source Code

Drag and Drop the Legend and Maintain the Position

Load the required files

To start, we must load some files, you can determine the files below.
[js]

[/js]

Creating UI elements

Now we need some UI elements to load the chart and show the drag and drop position. We will show the position values while the user drags and drops the legend, so that it looks more active.
[html]

Legend X:

Legend X:
[/html]

Creating options of chart

The next step we need is to set the options of the chart. Please find the following settings.
[js]
var options = {
title: {
text: ‘Worked hours in a week’
},
xAxis: {
categories: [‘Developing’, ‘Maitenance’, ‘Marketing’, ‘Business’, ‘Admin’]
},
series: [{
type: ‘column’,
name: ‘Monday’,
data: [3, 2, 1, 3, 4]
}, {
type: ‘column’,
name: ‘Tuesday’,
data: [2, 3, 5, 7, 6]
}, {
type: ‘column’,
name: ‘Wednesday’,
data: [4, 3, 3, 9, 0]
}, {
type: ‘column’,
name: ‘Thursday’,
data: [4, 3, 3, 9, 0]
}, {
type: ‘column’,
name: ‘Friday’,
data: [4, 3, 3, 9, 0]
}, {
type: ‘spline’,
name: ‘Thursday’,
data: [3, 2.67, 3, 6.33, 3.33],
marker: {
lineWidth: 2,
lineColor: Highcharts.getOptions().colors[3],
fillColor: ‘white’
}
}],
legend: {
enabled: true,
layout: ‘vertical’,
backgroundColor: ‘white’,
align: ‘left’,
verticalAlign: ‘top’,
y: 50,
x: 50,
borderWidth: 1,
borderRadius: 0,
title: {
text: ‘::Drag Me’
},
floating: true,
draggable: true,
zIndex: 20
}
};
[/js]

In the preceding code block we have set the series and other settings including the legend. Please note that we have set the draggable and floating property to true. You can customize all of these properties as you need to.
[js]
floating: true,
draggable: true,
[/js]

Now if you run your application, you will get output as follows.

Drag and Drop the Legend and Maintain the Position in Chart

So our application is working fine, isn’t it?

Changes in draggable-legend.js

To continue with the process, we must make some changes in the draggable-legend.js. You can see the changes below. If you download the source code attached, you can see the changes by default.
[js]
addEvent(chart.container, ‘mousemove’, function (e) {

});
[/js]

I will include some code for our purposes in the preceding function in draggable-legend.js. At the end of the specified function I am including the following code block.
[js]
$("#txtLegendX").val(options.x);
$("#txtLegendY").val(options.y);
sessionStorage.setItem("legendx", options.x);
sessionStorage.setItem("legendy", options.y);
[/js]

The purpose of that code block is to set the value to the session storage and the UI element. Now we will run our application and see the output.

Drag and Drop the Legend and Maintain the Position in Chart

Now if you drag and drop the legend somewhere else, you can see that the values specified in the text boxes has changed.

Drag and Drop the Legend and Maintain the Position in Chart

No we will check whether the values are updated to the session storage in the browser console.

Drag and Drop the Legend and Maintain the Position in Chart

Cool, it is updated, we are happy.

Now we need to retain this position even if the user reloads the chart, right? Normally what happens is, the chart will be loaded with the initial settings we have set in the option.

Maintain the legend position

To maintain the legend position, we must apply the legend position to the chart, we can take the values from the session storage where we already set the values.
[js]
if (sessionStorage.getItem("legendx") != null && typeof sessionStorage.getItem("legendx") != ‘undefined’ && sessionStorage.getItem("legendy") != null && typeof sessionStorage.getItem("legendy") != ‘undefined’) {
options.legend.x = parseInt(sessionStorage.getItem("legendx"));
options.legend.y = parseInt(sessionStorage.getItem("legendy"));
$("#txtLegendX").val(sessionStorage.getItem("legendx"));
$("#txtLegendY").val(sessionStorage.getItem("legendy"));
}
$(‘#container’).highcharts(options);
[/js]

We are checking the session storage values and applying values to the options and we provide that options to the chart. Sounds good? So our complete code for this implementation is as follows.

Advanced JQX Grid With All Functionality

SibeeshVenu — Wed, 29 Oct 2014 19:05:41 +0000

In this article we will see how we can implement or create a JQWidget’s JQX grid in our application. It is a client side grid which is good in performance and speed. We will see the advanced properties of a JQWidget JQX gris in this article.

This article has been selected as Asp.Net Community Article of the Day Sunday January 11 ,2015.

If you are new to the term JQX Grid then please find out the articles related to JQWidget category here: http://sibeeshpassion.com/category/products/jqwidgets/

If you need to bind the data source dynamically, please read here: http://sibeeshpassion.com/Convert-CellSet-to-HTML-table-And-From-HTML-To-Json-To-Array. For the past days I have been working on JQX Grid. Now I will share that Grid with all the functionality.

Advanced JQXGrid

Background

In my previous article, one member asked for some functionality. So I thought of sharing that info. Please note that I have not implemented all the functionalities. I have selected some important features that we may use in our programming life.

Using the code

As we discussed in the previous articles, we need a web application with all the contents of JQX Widgets (http://sibeeshpassion.com/working-with-jqx-grid-with-filtering-and-sorting/ ).

What is JQX Grid?

jqxGrid is powerful datagrid widget built entirely with open web standards. It offers rich functionality, easy to use APIs and works across devices and browsers. jqxGrid delivers advanced data visualization features and built-in support for client and server-side paging, editing, sorting and filtering.

What we need?

Simple HTML
[html]

[/html]

Include the extra UI elements
[html]

[/html]

Include Reference

[html]

[/html]

What we add new?
[js]

[/js]

This script is for adding the functionality of Paging :). You can add the functionality to the grid as
[js]
pageable: true.
[/js]

And if you want different stylish paging then you can set that like this:
[js]
pagermode: ‘simple’,
[/js]
[js]

[/js]

This script is for adding the functionality of Editing :). You can add the functionality to the grid as
[js]
editable: true.
[/js]
[js]

[/js]

These scripts are for adding the functionality of Hierarchy columns. If we want to separate the data in the column header then you can include the following scripts.
[js]

[/js]

When you want to export your grid to any formate, please include those scripts. You can implement the same just like the following:
[js]
$(“#excelExport”).jqxButton({ theme: theme }); //Assign styles to the button
$(“#xmlExport”).jqxButton({ theme: theme });
$(“#csvExport”).jqxButton({ theme: theme });
$(“#tsvExport”).jqxButton({ theme: theme });
$(“#htmlExport”).jqxButton({ theme: theme });
$(“#jsonExport”).jqxButton({ theme: theme });
$(“#excelExport”).click(function () {
$(“#jqxgrid”).jqxGrid(‘exportdata’, ‘xls’, ‘jqxGrid’); // To export to xlx
});
$(“#xmlExport”).click(function () {
$(“#jqxgrid”).jqxGrid(‘exportdata’, ‘xml’, ‘jqxGrid’); //To export to XML
});
$(“#csvExport”).click(function () {
$(“#jqxgrid”).jqxGrid(‘exportdata’, ‘csv’, ‘jqxGrid’); // To export to csv
});
$(“#tsvExport”).click(function () {
$(“#jqxgrid”).jqxGrid(‘exportdata’, ‘tsv’, ‘jqxGrid’); // To export to tsv
});
$(“#htmlExport”).click(function () {
$(“#jqxgrid”).jqxGrid(‘exportdata’, ‘html’, ‘jqxGrid’); // To export to html
});
$(“#jsonExport”).click(function () {
$(“#jqxgrid”).jqxGrid(‘exportdata’, ‘json’, ‘jqxGrid’); // To export to JSON
});
[/js]

If you want to print your grid:
[js]
$(“#print”).jqxButton();
$(“#print”).click(function () {
var gridContent = $(“#jqxgrid”).jqxGrid(‘exportdata’, ‘html’);
var newWindow = window.open(”, ”, ‘width=800, height=500′),
document = newWindow.document.open(),
pageContent =
‘\n’ +
‘\n’ +
‘\n’ +
‘\n’ +
‘jQWidgets Grid\n’ +
‘\n’ +
‘\n’ + gridContent + ‘\n\n’;
document.write(pageContent);
document.close();
newWindow.print();
});
[/js]

Now we need data to populate the grid, right? Since we are familiar with a simple header JQX Grid from the previous article, now we can go for a hierarchy column grid. So let’s say we have XML as follows:

[xml]

72
Formaggi Fortini s.r.l.
24 – 200 g pkgs.
32.3800
1996-07-04 00:00:00
59 rue de l-Abbaye
34.8000
Ravenna

Viale Dante, 75

Mozzarella di Giovanni

42
Leka Trading
32 – 1 kg pkgs.
32.3800
1996-07-04 00:00:00
59 rue de l-Abbaye
14.0000
Singapore

471 Serangoon Loop, Suite #402

Singaporean Hokkien Fried Mee

……..

……..

[/xml]

Please find the orderdetailsextended.xml from the source.

Implementing a JQX GRid with advanced features
[js]

[/js]

In the preceding script you can see a code part as follows:
[js]
columngroups:
[
{ text: ‘Product Details’, align: ‘center’, name: ‘ProductDetails’ },
{ text: ‘Order Details’, parentgroup: ‘ProductDetails’, align: ‘center’, name: ‘OrderDetails’ },
{ text: ‘Location’, align: ‘center’, name: ‘Location’ }
]
[/js]

This is where the column grouping is happening. And if you want to add a column under this column you can set that as follows:
[js]
{ text: ‘Name’, columngroup: ‘ProductDetails’, cellsalign: ‘center’, align: ‘center’, datafield: ‘ProductName’, width: 120 }
[/js]

You can specify this as needed and your data source.Now this is how our page looks like.
[html]

[/html]

That is all. We have successfully created a wonderful JQX Grid as in the following:

Advanced JQX Grid With All Functionality

Now you may think, why are those export buttons outside? It looks different, right? Now we can work on it. In the JQX Grid there is an option called showtoolbar, by setting this to true we can have a toolbar along with the grid. There we can bind all of these buttons if you want. So shall we start?
[js]
showtoolbar: true,
[/js]

Add that line to your JQX grid implementation. Next we need to append the UI elements to the tool bar, right?
[js]
rendertoolbar:function (toolbar) {
var me = this;
var container = $(“

”);
var input = $(‘

weight: bold;line-height: 28px; min-
width: 80px;padding: 3px 5px 3px 10px;color: #fff; “>Excel

div style=”background-color: #555555;float: left; font-weight: bold;line-
height: 28px; min-width: 80px;padding: 3px 5px 3px 10px;color: #fff; margin-
left: 3px;” id=”print” >Print’);
toolbar.append(container);
container.append(input);
}
[/js]

Add the preceding function also. 🙂 Now this is how your JQX Grid Implementation must be:
[js]
$(“#jqxgrid”).jqxGrid(
{
width: 900,
source: dataAdapter,
filterable: true,
sortable: true,
pageable: true,
autorowheight: true,
altrows: true,
columnsresize: true,
showtoolbar: true,
rendertoolbar: function (toolbar) {
var me = this;
var container = $(“

”);
var input = $(‘

height: 28px; min-width: 80px;padding: 3px 5px 3px 10px;color: #fff; “>Your First Div

width: 80px;padding: 3px 5px 3px 10px;color: #fff; margin-
left: 3px;” id=”Div2″ >Your Second Div

’);
toolbar.append(container);
container.append(input);
},
columns: [
{ text: ‘Supplier Name’, cellsalign: ‘center’, align: ‘center’, datafield: ‘SupplierName’, width: 110 },
{ text: ‘Name’, columngroup: ‘ProductDetails’, cellsalign: ‘center’, align: ‘center’, datafield: ‘ProductName’
, width: 120 },
{ text: ‘Quantity’, columngroup: ‘ProductDetails’, datafield: ‘Quantity’, cellsformat: ‘d’, cellsalign: ‘cente
r’, align: ‘center’, width: 80 },
{ text: ‘Freight’, columngroup: ‘OrderDetails’, datafield: ‘Freight’, cellsformat: ‘d’, cellsalign: ‘center’,
align: ‘center’, width: 100 },
{ text: ‘Order Date’, columngroup: ‘OrderDetails’, cellsalign: ‘center’, align: ‘center’, cellsformat: ‘d’, da
tafield: ‘OrderDate’, width: 100 },
{ text: ‘Order Address’, columngroup: ‘OrderDetails’, cellsalign: ‘center’, align: ‘center’, datafield: ‘Order
Address’, width: 100 },
{ text: ‘Price’, columngroup: ‘ProductDetails’, datafield: ‘Price’, cellsformat: ‘c2′, align: ‘center’, cellsa
lign: ‘center’, width: 70 },
{ text: ‘Address’, columngroup: ‘Location’, cellsalign: ‘center’, align: ‘center’, datafield: ‘Address’, width
: 120 },
{ text: ‘City’, columngroup: ‘Location’, cellsalign: ‘center’, align: ‘center’, datafield: ‘City’, width: 80 }
],
columngroups: [
{ text: ‘Product Details’, align: ‘center’, name: ‘ProductDetails’ },
{ text: ‘Order Details’, parentgroup: ‘ProductDetails’, align: ‘center’, name: ‘OrderDetails’ },
{ text: ‘Location’, align: ‘center’, name: ‘Location’ }
]
});
[/js]

Now your output looks like the following:

Advanced JQX Grid With All Functionality

What if you want to share this Grid with your friends? For that we have a jQuery share pluggin, Minimal jQuery Plugin For Social Share Buttons – Sharer.

Include the following files from the downloded rar from the preceding link

jquery.sharer.css

jquery.sharer.js

sharer.png

[js]

[/js]

Include the script to your page
[js]
$(“.social-buttons”).sharer();
[/js]

Add a div where you can see the share buttons
[js]

[/js]

Well, that’s all; you have now done everything. We can now see the page as,

Advanced JQX Grid With All Functionality

To set the page size add the following line to your grid settings:
[js]
pagesize: 50,
[/js]

To set the custom pagesize options add the following line to your grid settings:
[js]
pagesizeoptions: [‘5′,’10’,’15’,’20’,’30’,’40’,’50’],
[/js]

To allow resizing of the columns add the following line to your grid settings:
[js]
columnsresize: true,
[/js]

To allow column re-ordering options add the following line to your grid settings:

[js]
columnsreorder: true,
[/js]

Be sure that you added the jqxgrid.columnsreorder.js JavaScript file.

To allow an Excel-like filter add the following line to your grid settings:
[js]
filtermode: ‘excel’,
[/js]

Then you will get a filtering option as follows:

Advanced JQX Grid With All Functionality

To enable the tooltip add the following line to your grid settings
[js]
enabletooltips: true,
[/js]

To apply themes add the following line to your grid settings
[js]
theme: ‘metro’,
[/js]

Please be noted that you must include the style sheet accordingly, In this case you have to include the following
[html]

[/html]

You can find so many CSS in jqwidgets/styles folder.

To enable auto height add the following line to your grid settings
[js]
autoheight: true,
[/js]

To show the default filter icon always add the following line to your grid settings
[js]
autoshowfiltericon: false,
[/js]

Happy Coding 🙂
