Hello Sairam,

The best approach is to ajaxify the whole grid. Check out the following ajax settings.

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RgCheckSetUp">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RgCheckSetUp" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>
