PlaceHolder, TreeView, UserControl
-
Hi all I'm trying ing to create usercontrols dynamically and add them into a placeholder. During a postback i got the following error " Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate 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. " Is there any way I can solve this problem?

This question should be asked in the ASP.NET forum[^]. This forum is for questions specific for the C# language.
