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?

I had the same issue and I was killing myself. Apparently I had two <form runat="server">...</form>. You are allowed to have two <form> tags but only one of them can have runat="server" attribute.

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).

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.

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