I forgot "EnableLinqExpressions = False".

Now it works!

I kept "EnableLinqExpressions = False". still I am facing the same problem. Please help.

Hi Shal,

Can you confirm that you are not calling the DataBind() method of the Grid anywhere on the problematic page?

In case you are binding the control via simple data binding, I would advise that you switch to Advanced Data-binding (Using NeedDataSource Event), ensuring that DataBind() mehod is not called anywhere in the code. 

If this does not help, you could share the markup of the grid and the server code related to it, so we would be able to provide you with a more accurate information.
