In this post we will see how we can implement radio button selection feature to jQWidgets jQXGrid. As of now in JQXGrid, we don’t have this functionality yet, but still we can do it our self by using check box selection which is already available. We will load the grid with sample data and implement the radio button selection. If you are new to JQX Grid, you can see some tips here. I hope you will like this.

Download Source Code

You can always download the source code from here: Radio button selection in JQXGrid

Background

I am using JQXGrid in one of my project, where I wanted to implement the radio button selection, when I talked with JQXGrid development team, I was said that the functionality is not yet available. But they have given an option as selectionmode: ‘checkbox’ with the help of that property we can implement the requirement. As you know, to load a jQWidget JQX Grid, there you need the following things as mandatory.

Using the code

First of all, load the needed references. You can download the needed files from here.

[html]
<link rel="stylesheet" href="jqwidgets/styles/jqx.base.css" type="text/css" />
<script src="jquery-2.2.3.min.js"></script>
<script type="text/javascript" src="jqwidgets/jqxcore.js"></script>
<script type="text/javascript" src="jqwidgets/jqxdata.js"></script>
<script type="text/javascript" src="jqwidgets/jqxbuttons.js"></script>
<script type="text/javascript" src="jqwidgets/jqxscrollbar.js"></script>
<script type="text/javascript" src="jqwidgets/jqxmenu.js"></script>
<script type="text/javascript" src="jqwidgets/jqxgrid.js"></script>
<script type="text/javascript" src="jqwidgets/jqxgrid.edit.js"></script>
<script type="text/javascript" src="jqwidgets/jqxgrid.selection.js"></script>
<script type="text/javascript" src="jqwidgets/jqxgrid.pager.js"></script>
<script type="text/javascript" src="jqwidgets/jqxlistbox.js"></script>
<script type="text/javascript" src="jqwidgets/jqxdropdownlist.js"></script>
<script type="text/javascript" src="jqwidgets/jqxgrid.sort.js"></script>
<script type="text/javascript" src="jqwidgets/jqxcheckbox.js"></script>
<script type="text/javascript" src="jqwidgets/jqxgrid.columnsresize.js"></script>

Now, we are going to set our data source, this time we will use a XML file as data source.

You can get the full data from the file orders.xml from the solution attached.

Now create a div element where we can bind the grid.

[html]
<div id=’jqxWidget’ style="font-size: 13px; font-family: Verdana; float: left;">
<div id="jqxgrid">
</div>
</div>
[/html]

Now we will define our grid as follows.

[js]
$("#jqxgrid").jqxGrid(
{
width: 850,
height: 450,
source: dataAdapter,
sortable: true,
selectionmode: ‘checkbox’,
altrows: true,
ready: function () {
$(‘#columntablejqxgrid .jqx-checkbox-default’).hide();
},
columns: [
{ text: ‘Ship Name’, datafield: ‘ShipName’, width: 250 },
{ text: ‘Shipped Date’, datafield: ‘ShippedDate’, width: 100, cellsformat: ‘yyyy-MM-dd’ },
{ text: ‘Freight’, datafield: ‘Freight’, width: 150, cellsformat: ‘F2’, cellsalign: ‘right’ },
{ text: ‘Ship City’, datafield: ‘ShipCity’, width: 150 },
{ text: ‘Ship Country’, datafield: ‘ShipCountry’ }
]
});
[/js]

As you can see we have applied dataAdapter as the source, below is the definition for your data adapter.

[js]
var dataAdapter = new $.jqx.dataAdapter(source);
[/js]

Now we will create the source object as follows.

[js]
var source =
{
datatype: "xml",
datafields: [
{ name: ‘ShippedDate’, map: ‘m\\:properties>d\\:ShippedDate’, type: ‘date’ },
{ name: ‘Freight’, map: ‘m\\:properties>d\\:Freight’, type: ‘float’ },
{ name: ‘ShipName’, map: ‘m\\:properties>d\\:ShipName’, type: ‘string’ },
{ name: ‘ShipAddress’, map: ‘m\\:properties>d\\:ShipAddress’, type: ‘string’ },
{ name: ‘ShipCity’, map: ‘m\\:properties>d\\:ShipCity’, type: ‘string’ },
{ name: ‘ShipCountry’, map: ‘m\\:properties>d\\:ShipCountry’, type: ‘string’ }
],
root: "entry",
record: "content",
id: ‘m\\:properties>d\\:OrderID’,
url: url
};
[/js]

As the grid definition is over,it is time to run our application and check whether the grid is loading fine or not.

Grid with check box selection

what do you see? You are able to do multiple selection right? But what do we needed? A radio button selection, isn’t it? So we are suppose to able to select only one row right?. This is why, we haven’t done the needed implementation yet. Let us add some script then.

[js]
$(‘#jqxgrid’).on(‘rowselect’, function (event) {
// event arguments.
var args = event.args;
// row’s bound index.
var rowBoundIndex = args.rowindex;
var selectedIndexes = $(‘#jqxgrid’).jqxGrid(‘selectedrowindexes’);
for (var i = 0; i < selectedIndexes.length; i++) {
if (rowBoundIndex !== selectedIndexes[i]) {
$(‘#jqxgrid’).jqxGrid(‘unselectrow’, selectedIndexes[i]);
}
}
});
[/js]

We are just deleting the other row selection in the event rowselect. Now run your application again, I am sure you will be able to select only one row at a time.

Now we can see the complete code.
