I just upgraded all my RadSplitters/RanPanes to the latest Prometheus version.  I did this by removing the old dll and adding in the new one.  All of the controls show "Failed to create designer "Telerik.Web.UI.RadSplitter, Telerik.Web.UI, Version=2007.2.1107.0......." in designer view. 

I am using the hotfix versions of the controls.  Do you know what might be happening?

Hello Scott,
The code for our controls in design view is in the Telerik.Web.Design.dll. Just add a reference to that DLL and the problem should disappear.

I have this problem with 2009.1.311.20.  I tried using GAC and not, installed VS2008 SP1 and still no luck.
Any ideas?
Thanks
John

Hello John,

Make sure that you have the same assembly version referenced in the Web.config, in the Bin folder and in the GAC. You should have all the same assembly everywhere and also it is better if you have the fully qualified name in the Web.config references. If you have all this ensured, you should not experience problems with the designer.


Best wishes,
Svetlina

Thanks
Atanas http://blogs.telerik.com/AtanasKorchev/Posts/09-03-06/Meet_Telerik_Web_Design_dll.aspx lead me in my search.  I found Telerik.Web.Design ...20 and ...35 in C:\WINDOWS\assembly.  Couldn't uninstall these assemblies until 2009.1.311 .exe was removed.  After scrubbing the new install and removing both Design assemblies from the assembly folder I manually set ...35 in the GAC and Telerik.Web.UI in my project Bin.  All is good.
