Hi, I was wondering if there was a way to add the radajaxmanager specifically to the sort command of a radgrid.  I am pretty sure this has to be done pro grammatically using Vb.net or C#.  For example here is an example where I specifically added the radajax functionality to a LinkButton control within a radgrid programmatically using VB.net.....

 Protected Sub Radgrid_AddRemoveProvider_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Radgrid_AddRemoveProvider.PreRender
       For Each item As GridDataItem In Radgrid_AddRemoveProvider.MasterTableView.Items
    
            Dim btnAddProvider As LinkButton = DirectCast(item.FindControl("btnAddProvider"), LinkButton)
            Dim btnRemoveProvider As LinkButton = DirectCast(item.FindControl("btnRemoveProvider"), LinkButton)

            'Add radajax functionality to only specific controls within radgrid
            radAjaxManager1.AjaxSettings.AddAjaxSetting(btnAddProvider, Radgrid_AddRemoveProvider)
            radAjaxManager1.AjaxSettings.AddAjaxSetting(btnRemoveProvider, Radgrid_AddRemoveProvider)
        Next

End Sub

Since the 'Sorting' within a radgrid is not a control, I do not know how to add it to the ajaxmanager.  Please Assist...

Hello Aret,

You could enable ajax only on sorting command using the following approach:
  mark-up:
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" ClientEvents-OnRequestStart="requestStart">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadGrid1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

  JavaScript:
function requestStart(sender, args) {
    if (args.get_eventArgument().indexOf("Sort") < 0)
        args.set_enableAjax(false);
}

That should do the trick.
