C#.NET ASP.NET error

Question

Hi,

I have an error comes up in aspx page:

The state information is invalid for this page and might be corrupted.

What would be the problem?

Regards

Answer 1

This can happen once the ViewState is corrupted. Also is there ViewState Validation enabled i.e. EnableViewStateMAC=true in Page?

Answer 2

I think this also happens if you post one page's viewstate to another page - you have to wire this up first or post back to the same page and redirect the request to the other page on the server side.

Answer 3

This can happen when you're rebuilding the control tree on postback and it's not exactly the same as the control tree when you were databinding/loading the page the first time (before postback).
