I'm hanging with the same problem. 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.

To find out why, I made some little changes, first I defined MyDropDownList: public class MyDropDownList : DropDownList { protected override void LoadViewState(object savedState) { base.LoadViewState(savedState); postback dynamic control creation - selectedindex by default points to zero 2., the viewstate for the selectedindex on the same dropdown before the postback happened is zero Consequence which leads to Setting the EnableViewState = false of the control helps.ReplyDeleteeasankaFebruary 16, 2009 at 11:13 AMthe artical was really help full in my case.. http://smartnewsolutions.com/failed-to/failed-to-load-viewstate-control-tree-into-which.html I'm using ASP.NET Dynamic Data and I get this same error when I am editing an entity (it's a DetailsView control) and instead of saving my chances I click Cancel.
