WSS+SP2 + .NET 2.0 + Unghosted Page --> Problem?

  Asked By: Marcella    Date: Nov 05    Category: Sharepoint    Views: 1122

I have WS SP2 + .Net 2.0 framework, with WSS running on .Net 2.0. Everything
works fine. Until I have a unghosted page... when I try to add a web part using
the web interface I get the following exception:

Invalid postback or callback argument. Event validation is enabled using <pages
enableEventValidation="true"/> in configuration or <%@ Page
EnableEventValidation="true" %> in a page. For security purposes, this feature
verifies that arguments to postback or callback events originate from the server
control that originally rendered them. If the data is valid and expected, use
the ClientScriptManager.RegisterForEventValidation method in order to register
the postback or callback data for validation.

I have the enableEventValidation set to false, as configured using the command:

stsadm.exe -o upgrade -forceupgrade -url http://URLOftheVirtualServer
<http://URLOftheVirtualServer>

I tried to add this setting to other web.config's and to the machine.config, but
to no avail.

Seems like the SharePoint safe mode parser (executed on unghosted apsx pages) is
behaving different from the normal ASP.NET page rendere.

When I modify the pages using FrontPage there is no problem.

Any ideas? I would hate to go back to the 1.1 FrameWork, because now I can write
my web parts using SonOfSmartPart and the full functionality of the ASP.NET 2.0
framework.
