Hello Ankit,

Please remove the ASP:UpdatePanel and ajaxify the grid thouggh the RadAjaxManager by adding a setting where the grid updates itself.
Note that it is strongly recommended not to use more than one ajax control for ajaxifying the same page content.

Best wishes,

Hi Ankit,

What if you replace the ToolkitScriptManager with RadScriptManager, do you observe the same issue? If yes, I would ask you to add the provided code to a runnable sample and open a formal support ticket so I can forward it to our developers for further research.
