From the information what you gave I would suggest that this could be due to that the Viewstate of the page is changed by dynamically added controls during any ajax requests. Can you share where the button control has been placed? Does it do any ajax postback?

As Lakxman said, it is usually because the form has been changed dynamically on the client side making the viewstate invalid for what is getting sent back to the server.
