I am porting a 3.5 web app to 4.0. This app started as a AjaxToolkit and Telerik was added later. I got 4.0 dll added and the web site built, but my RadWindows when I close via the following:
Protected Sub CloseForm()
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "Close", "GetRadWindow().Close();", True)
The window closes and relaunches. What to do?
