    I just installed the B2 and added new dlls to my current project. In Blend, If I go to a page that has a Tab Control there, I get error message "Cannot create an instance or RADTabControl". With this error, I can't see the control or the content at design time to work on the page. Any suggestion or workaround?

    Hello Ben,

    There was an update of the controls that resolves the design-time issues with Blend. Please download the controls again.

    I am sorry for any inconvenience caused.

    Ben, Miroslav

    I had this same problem yesterday. What I found was that in VS I had Telerik.Windows.Controls.Navigation as my only Telerik assembly. It worked fine in VS but opening in blend produced the error Ben found. If I added Telerik.Windows.Controls as a reference in VS I could open the page in blend.

    Hi,
    I was having the same problem as mentioned by Ben with "Telerik_RadControls_for_Silverlight_Beta2_Trial" .
    I took the latest download "Telerik_RadControls_for_Silverlight_RC0_Trial".
    Now I am not able to drag the TabControl on the Expression Blend 2.5 June 2008 preview. Every time I do it, I get the following error :

    ---------------------------
    Target Invocation Exception
    ---------------------------
    Inner exception: System.TypeInitializationException: The type initializer for 'Telerik.Windows.Controls.RadTabControl' threw an exception. ---> System.MissingMethodException: Method not found: 'Void System.Windows.PropertyMetadata..ctor(System.Object, System.Windows.PropertyChangedCallback)'.

       at Telerik.Windows.Controls.RadTabControl..cctor()

       --- End of inner exception stack trace ---
    ---------------------------
    OK  
    ---------------------------


    I have silverlight 2 Beta 2 on my machine and for Telerik have the dlls from the download of  "Telerik_RadControls_for_Silverlight_RC0_Trial".
    Regards,
    Sandeep

    Sandeep, be sure have the following setup correctly:

    .Net 3.5 SP1
    VS 2008 SP1
    SL RC0
    Blend 2 SP1
    Telerik RC0 compatible controls (latest one to pickup).

    Try the tab with the above combo and see if you still have problem.
