Implement Radio Button Selection In JQWidgets JQXGrid

In this post, we will see how we can implement the radio button selection feature in jQWidgets jQXGrid. In JQXGrid, we don’t have this functionality yet, but we can do it ourselves by using the check box selection which is already available. We will load the grid with the 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 projects where I want to implement the radio button. When I talked with the JQXGrid development team, I was told that the functionality is not yet available but they have given an option as a selection mode: ‘checkbox’, with the help of which we can implement the requirement. As you know, to load a jQWidget JQX Grid, you need the following mandatory things:

  • Datafields
  • Columns
  • Local data or Server side data

Using the code

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

  1. <link rel="stylesheet" href="jqwidgets/styles/jqx.base.css" type="text/css" />  
  2. <script src="jquery-2.2.3.min.js"></script>  
  3. <script type="text/javascript" src="jqwidgets/jqxcore.js"></script>  
  4. <script type="text/javascript" src="jqwidgets/jqxdata.js"></script>  
  5. <script type="text/javascript" src="jqwidgets/jqxbuttons.js"></script>  
  6. <script type="text/javascript" src="jqwidgets/jqxscrollbar.js"></script>  
  7. <script type="text/javascript" src="jqwidgets/jqxmenu.js"></script>  
  8. <script type="text/javascript" src="jqwidgets/jqxgrid.js"></script>  
  9. <script type="text/javascript" src="jqwidgets/jqxgrid.edit.js"></script>  
  10. <script type="text/javascript" src="jqwidgets/jqxgrid.selection.js"></script>

  16. <script type="text/javascript" src="jqwidgets/jqxgrid.columnsresize.js"></script>  
Now, we are going to set our data source.This time, we will use an XML file as a 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.

  1. <div id='jqxWidget' style="font-size: 13px; font-family: Verdana; float: left;">  
  2. <div id="jqxgrid">  
  3. </div>  
  4. </div>  
Now, we will define our grid as follows.
  1. $("#jqxgrid").jqxGrid  
  2. ({  
  3.     width: 850,  
  4.     height: 450,  
  5.     source: dataAdapter,  
  6.     sortable: true,  
  7.     selectionmode: 'checkbox',  
  8.     altrows: true,  
  9.     ready: function()  
  10.     {  
  11.         $('#columntablejqxgrid .jqx-checkbox-default').hide();  
  12.     },  
  13.     columns: [  
  14.       {  
  15.         text: 'Ship Name',  
  16.         datafield: 'ShipName',  
  17.         width: 250  
  18.     }, {  
  19.         text: 'Shipped Date',  
  20.         datafield: 'ShippedDate',  
  21.         width: 100,  
  22.         cellsformat: 'yyyy-MM-dd'  
  23.     }, {  
  24.         text: 'Freight',  
  25.         datafield: 'Freight',  
  26.         width: 150,  
  27.         cellsformat: 'F2',  
  28.         cellsalign: 'right'  
  29.     }, {  
  30.         text: 'Ship City',  
  31.         datafield: 'ShipCity',  
  32.         width: 150  
  33.     }, {  
  34.         text: 'Ship Country',  
  35.         datafield: 'ShipCountry'  
  36.     }]  
  37. }); 
As you can see, we have applied dataAdapter as the source. Below is the definition for your data adapter.
  1. var dataAdapter = new $.jqx.dataAdapter(source);  
Now, we will create the source object as follows:
  1. var source =  
  2.     {  
  3.     datatype: "xml",  
  4.     datafields: [{  
  5.         name: 'ShippedDate',  
  6.         map: 'm\\:properties>d\\:ShippedDate',  
  7.         type: 'date'  
  8.     }, {  
  9.         name: 'Freight',  
  10.         map: 'm\\:properties>d\\:Freight',  
  11.         type: 'float'  
  12.     }, {  
  13.         name: 'ShipName',  
  14.         map: 'm\\:properties>d\\:ShipName',  
  15.         type: 'string'  
  16.     }, {  
  17.         name: 'ShipAddress',  
  18.         map: 'm\\:properties>d\\:ShipAddress',  
  19.         type: 'string'  
  20.     }, {  
  21.         name: 'ShipCity',  
  22.         map: 'm\\:properties>d\\:ShipCity',  
  23.         type: 'string'  
  24.     }, {  
  25.         name: 'ShipCountry',  
  26.         map: 'm\\:properties>d\\:ShipCountry',  
  27.         type: 'string'  
  28.     }],  
  29.     root: "entry",  
  30.     record: "content",  
  31.     id: 'm\\:properties>d\\:OrderID',  
  32.     url: url  
  33. };  
As the grid definition is over, it is the time to run our Application and check whether the grid is loading fine or not.

application
Grid with check box selection:

What have you noticed? You are able to do the multiple selection, right? But what do we need? A radio button selection, isn’t it? Hence, we are supposed to select only one row, right? This is why,we haven’t done the needed implementation yet. Let us add some script then, as follows:

  1. $('#jqxgrid').on('rowselect', function(event)   
  2. {  
  3.     // event arguments.  
  4.     var args = event.args;  
  5.     // row's bound index.  
  6.     var rowBoundIndex = args.rowindex;  
  7.     var selectedIndexes = $('#jqxgrid').jqxGrid('selectedrowindexes');  
  8.     for (var i = 0; i < selectedIndexes.length; i++)  
  9.     {  
  10.         if (rowBoundIndex !== selectedIndexes[i])  
  11.         {  
  12.             $('#jqxgrid').jqxGrid('unselectrow', selectedIndexes[i]);  
  13.         }  
  14.     }  
  15. });  
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.

A blog isn’t a blog without comments, but do try to stay on the 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.
