Hi all,

I have followed the following tutorial to use multiview control.

www.adefwebserver.com/DotNetNukeHELP/Misc/ModuleNavigationOptions.htm

In one of the views, I have choices to load one of two user controls. When I first load one user control, it works. But the next time I do select to load another user control, shows the error:

A critical error has occurred.
Failed to load view_state. The control tree into which view_state is being loaded must match the control tree that was used to save view_state 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.

 Has anyone experienced it earlier? What could be the solution? Thanks a lot.
