Hello Tsvetina I went through your example. But what I need to achieve is a way to use Jquery Ajax where I can manually mention the page URL Of where my page method exist. Similar to the code example provided by jayesh. Where he states this following code jQuery.ajax({ type: 'POST', contentType: 'application/json; charset=utf-8', data: '', dataType: 'JSON', url: 'Default.aspx/BindGrid', success: function (result) { How do I achieve sorting , paging using this method ?

Or is there a generic way to have all Telerik contorls ajax traffic route to a specific page method of your choice ?
I need to figure this out, since Im building a Single Page Application, where the html content of multiple pages are downloaded on to say a Default.aspx.
Hence any interaction with my Telerik controls need to hit the appropriate Code behind page like Form1.aspx , from the base page Default.aspx.

Generally I can do this with jQuery's Ajax by specifying manually in the URL part the page path of the web method as shown below.

$.ajax({
        type: "POST",
        url: MyWebMethodPagePath + "/" + webMethodName,
        contentType: "application/json; charset=utf-8",
        data: paramList,
        dataType: "json",
        success: successFn,
        error: errorFn
    });

Let me know if there's a generic technique I can use for my Telerik Controls aswell.
If not atleast specific to Telerik Grids where I can Sort and provide paging.

Hello Nikil,

In order to achieve your scenario you could subscribe to RadGrid OnCommand client-side event and route your request from there. Note that there is no build in mechanism in RadGrid or any other Telerik control for routing ajax traffic.

<ClientSettings>

<ClientEvents OnCommand="GridCommand" />

</ClientSettings>

function GridCommand(sender, args)

{

if (args.get_commandName() === "Sort")

{

// your routing logic here

}

Hi Subodh,

You could achieve the desired functionality by following the approach shown in the demo below.

http://demos.telerik.com/aspnet-ajax/grid/examples/client/databinding/defaultcs.aspx

The idea is to use the updateGrid function which accepts an JavaScript Array which will bind to the RadGrid.

function updateGrid(result)

{

var tableView = $find("<%= RadGrid1.ClientID %>").get_masterTableView();

tableView.set_dataSource(result);

tableView.dataBind();

}
