Hello Harin,

Could you please let me know what the ajax setting you are implementing are? Please elaborate a bit more on your scenario. Also it will be helpful if you post your aspx page markup with the related code behind file or open a regular support ticket and send us a small runnable example which demonstrates the described issue. Thus we will be able to gather more details about your scenario, debug the application and investigate the problem.
Looking forward for your reply.

Hi,

Could you please try wrapping the GridView in a regular asp Panel and add only a setting in which that panel updates itself like this:

        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="GridViewPanel">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="GridViewPanel" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>
  
<asp:Panel ID="GridViewPanel" runat="server">
  <asp:GridView..............>
</asp:GridView>
</asp:Panel>

Hi Rohinikumar,

As the previously provided suggestions did not help it will be best if you could open a regular support ticket and send us runnable version of your application which demonstrates the problem. Thus we will be able to inspect it locally and do our best to provide a proper solution.

Thank you for your cooperation.
