Hello Priya,

From the exception trace it seems that the update panel which wraps the grid instance cannot be unregistered by the ScriptManager due to the reason specified in the message.

Have you ajaxified the grid by means of MS UpdatePanel? Does the same issue occur if you replace it with standard GridView control and enable paging for it? The answers to these questions can help us determine the cause of the issue to eliminate it.

I will also appreciate if you paste the problematic grid definition along with its code-behind in this forum post. I will review it and will advice you further.

Best regards,
