    I am running the Q2 version of Telerik Rad WPF and cannot open the xaml file Expressoin Blend 4. I have never tried it again, so I am wondering if I should be able to or not. The error I am getting is, The element "[RadTabControl]" could not be displayed because of a problem with Telerik.Windows.Controls.RadTabContol: Cannot create an instance of "RadTabControl".

    The inner exception is
    The type initializer for 'Telerik.Windows.Control.RadTabControl' threw an exception.

    Below that is could not load type 'Telerik.Windows.Controls.ThemeResourceKey' from assembly 'Telerik.Windows.Controls, Version 2011.2.712.1040, Culture=Netral, PublicKeyToken= 5803cfa389c90ce7

    Is this a configuration issue, or are the telerik controls just not compatable with Expression Blend 4?

    Hello Randy,

    The RadControls for WPF can be fully customized using ExpressionBlend and we are not aware of any issues when displaying a UserControl/Window containing a RadTabControl in Blend. I attached a sample project that was created in ExpressionBlend 4 and you should be able to open and view it on your side as well.

    In your case the issue might be caused by different versions of the assemblies referenced in your project. Can you give us more details about that. Also, if you can open a support thread and send us a sample project reproducing the issue we will look into it and get back to you with a solution.

    All the best,
