    I'm using Visual Studio 2012 Ultimate bit at work. The OS is Windows 7 x32. We have a large web application (Asp Web Form based) which relies heavily on the telerik controls. We also use JustCode, and Telerik reports.

    However recent updates to Q2 2013 has caused serious problems. Now in aspx files, just code underlines red on all telerik controls and switching to the design mode gives error on all the controls. I've tried various solutions and even searched the forums to no avail. 

    Here is the screenshot of the VS 2012, webpage with telerik controls in design mode

    any solutions?


    Update: (Fixed the issue of all designers except Telerik Report viewer)

    I resolved the issue by checking out all the files, and running the upgrade Wizard. However the Upgrade Wizard was unable to add the httpHandler for the report in web.config. so I added the following line:

    <add path="Telerik.ReportViewer.axd" verb="*" type="Telerik.ReportViewer.WebForms.HttpHandler"
          validate="false" />

    even after which the report viewer designer kept giving error in design mode but when executed the app the report viewer buttons started displaying in the page in a weird way. all the buttons were displayed as 100% width and each one displayed on a single line.
