Hi,

I am writing a Telerik asp.net web site and having a problem I haven't seen before.

Start VS2008, open first aspx file. I can add Telerik controls. Switch to another aspx document attempt to add a Telerik control and a huge amount of mark up is inserted rather than the control (and does not function). Doesn't matter which aspx file I start with, when I switch to another one, I get the gibberish if I insert a control.

Could be unrelated: I recently "moved" my Documents folder to another drive.

This is a snippet of the load of text inserted rather than a valid control.

Hello,

I found a reference to a similar issue in our forums - http://www.telerik.com/community/forums/aspnet/general-discussions/vs-2008-issue.aspx. Unfortunately, the original poster did not post whether he managed to solve the problem eventually.

Searching in Google with the error details yielded no usable results - almost all people, who reported the problem say it happens when they try to add ASP.NET AJAX controls in VS design mode. If you are not able to resolve the problem by other means, I think the only possible solution is to uninstall and then reinstall VS 2008 (and ASP.NET AJAX 1.0, if your application is built with .NET 2.0).


Sincerely yours,

I'm also having this problem but in VS2010 RTM.  I used the Telerik addin to create the page.  This  is happening with 2010.1.415.40.

Hello Kevin,

I was able reproduce this issue with VS2010. These are some kind of shadows, not real RadControls. My best guess currently is that on installation VS2010 tries to import any custom control groups from VS2008 toolbox and fails. The fix is to remove the shadow controls and to reinstall RadControls for ASP.NET AJAX. Alternative route is to drag and drop the Telerik.Web.UI.dll on the ToolBox.

Best wishes,
