I am getting this error.
But i cant find out the reason why i am getting this error

Failed to load viewstate.

The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.

For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request

I got the solution

Can you please tell me how you solved 'Failed to Load viewstate' Issue.

Very Very Urgent .
Thanks in Advance
