Server Error in '/' Application.

The View State is invalid for this page and might be corrupted.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

   System.Web.UI.Page.LoadPageStateFromPersistenceMedium() +151

Thanks, Mart.

Isn't this somesort of a feature in the web.config file? If so, try turning it off, or update your .NET framework.

You probably uses Server.Transfer in your page,
if yes follow the link below to resolve this problem:

http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/Q316/9/20.asp&NoWebContent=1 - http://support.microsoft.com/default.aspx?scid=http://suppor t.microsoft.com:80/support/kb/articles/Q316/9/20.asp&NoW ebContent=1

Nope and Nope, I tried using the header EnableViewState="false" and it still happens and it doesnt use server.transfer.

Any other ideas?

Thanks, Mart.

Try this other fix from Microsoft:

Thanks, but there has to be a pernament way... How can MS just tell you to change the URL???  Its there error they should release a patch!

I mean how I am supposde to tell my visitors to change the URL if they get a viewstate error!

Does anyone know a trick to fix this?

Thanks, Mart

Hello Mart,

Thanks, but there has to be a pernament way...

Did you acquired the hotfix from Microsoft like they suggest in the link i give you ?  An other thing you can do is to upgrade to Framework 1.1 cause this bug is for Framework 1.0

I mean how I am supposde to tell my visitors to change the URL if they get a viewstate error!

Is this the hotfix from Microsoft ??? What i know about this bug is that only occurs on production server so your visitors won't see it. But you see that error and i understand your frustation. Last suggestion from me is to recreate an other project with vs.net and imports your files.

1. Create an .aspx page, and then add a Button server control to the page.
2. Use the following URL to open the page in your browser:

   http://localhost/myweb/page.aspx

3. Modify the .aspx page so that the page is recompiled.
4. Open a new instance of the browser.
5. Use the following URL (notice the difference in the capitalization of "myweb") to open the page in the new instance of the browser:

   http://localhost/MyWeb/page.aspx

6. Return to the original instance of the browser, and then click Submit. Notice that you receive the error message that is listed in the "Symptoms" section.

Why don't you tell your host to update his framework or you're gone?

My god Mart in your last post you are just reproduce the bug ??? They give us those 6 steps to show us how to reproduce the behavior. Look in the RESOLUTION section instead:

RESOLUTION

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix...

Like i said before, usually this bug only occurs on production server that's why you see localhost in the Steps to Reproduce the Behavior section. But if you have that bug with your hosting provider, like Diep-Vriezer said, you better ask them to update to framework 1.1 or leave
