    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...

    Hello Yun,

    Please check if the Telerik.Web.UI.dll file is in the bin folder of your project. If it is there, you might need to remove the Read-only attribute from the physical file before you try to compile your project. Visual Studio might need to overwrite the file when you drag & drop the control from the toolbox and if it cannot, it will complain that the file cannot be found - even if it is in the bin folder.

    Moreover you can try to add your assembly manually when go to the new Prometheus tab in the toolbox, right click and "Choose Items...". Then on the .NET Framework Components tab click "Browse" and select the Telerik.Web.UI.dll file.

    Kind regards,
    the Telerik team
