Hi,

I am new to RAD controls. I have VS 2008, .NET 3.5 and installed the trial version of Telerik RAD controls for ASPNET AJAX Q1 2009. Per the Help documents I created a new .NET/C# Web project, added Script Manager to the default web page and trying to add RAD Tree View control. I am getting this error message:

Error Creating Control - RadTreeView1

Failed to create designer 'Telerik.Web.UI.RadTreeView, Telerik.Web.UI, Version=2009.1.402.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4'

I have added references to Telerik.Web.UI.dll and Telerik.Web.Design.dll

Am I missing something? Please help. Thanx.

Never mind. I fixed it.

I added the above two dlls to GAC, closed/reopened project in Visual Studio and that seems to fix it.

Hello Joshi,

can you please tell me how you fixed the error. I have the same one.
Where can I find the GAC - I am an absolute Newbie?

Thx for help.
