I have just signed in the Client.net and downloaded the trial version of RadControls Q3 2007 SP2 trial.exe and RadControls Prometheus, then I started the visual studio 2005 program (with AjaxControlExtension and .net Framework 2.0 already installed), then I opened an exsiting web site from an folder(including the RadControls folder in the root) in my hardisk which was created by my teamates and copied to mine computer. I just find a problem, that when I try to open the master page in design view, there appears "error creating controls"----for RadScriptManager and RadStyleSheet and Rad Splitter with message "unregnized tag..." "adding reference to System.Web.UI..."
what should I do to solve the problem? Hope any help...
