HI,

So can you please suggest where am I doing Mistake

Hello Rama,

How is the user control with the grid added on the page, declaratively or dynamically? Please share the ascx and ascx.cs/ascx.vb code for further check.

Hi Rama,

I can see that the user controls is not declaratively added to the ASP:UpdatePanel on the page. However, can you elaborate how are you adding it?
Additionally, I suggest that you use advanced data-binding for the grid, instead of the simple data-binding approach and see if it makes any difference.

Best wishes,
