    After upgrading I get Failed to create designer 'Telerik.Web..... on all Telerik controls.

    The only way I can get the controls to work is to down grade them.  What do I need to do to get them to work?

    Using Telerik version 2011.1.519.35
    only working version looks like 2010.1.519.35 located in the installation folder all other version are in the Download folder. 
    Using VS2010 Prem, Windows 7 Ent. all service packs installed and up to date.

    Hello Kris,

    I think that the information from this documentation topic will help you eliminate the design-time error you encountered.

    Best regards,
    the Telerik team

    I resolved the problem!!!

    I use the function Telerik --> RadControls for ASP:NET --> Launch Toolbox and use the DEV InstallFolder and it's OK!

    I hope that works
