Hi 

I'm making changes to a project I mad a few months ago.

But when I open the designer all of my controls have errors.

"Error Creating Control - RadAjaxManager1Failed to create designer 'Telerik.Web.UI.RadAjaxManager, Telerik.Web.UI, Version=2013.3.1114.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4"

That is just one example.

I've tried updating, and just about everything else that I've found on these forums and nothing has fixed the problem.

Please help.

Grant.

Hi Princy 

Yes i did follow all of those steps and still the same.

For some odd reason, after another update it did seem to fix the problem,
but now visual studio crashes on designer and when I restart.

Please help me with this.

Hello Grant,

Could you please provide some more details about what steps have you tried. Did you install the latest version using the installer? Do you have other versions of the RadControls on your machine? Also please note that the Telerik.Web.UI.dll requires Telerik.Web.Design.dll of the same version in the Gac. Can you please confirm that you have the same version of dlls? Here are the steps for that:

- Start a Visual Studio Command Prompt
- Type the following command and hit ENTER:
gacutil /l Telerik.Web.Design

Looking forward for your reply.

Regards,
Radoslav
