  I'm trying to figure out a good way to get a theme applied at design time. I followed someones suggestion to create a class like this and added it to the resources in my App.xaml.
  

  public class TelerikThemeManager : DependencyObject

  {

      public TelerikThemeManager()

      {

          StyleManager.ApplicationTheme = new MetroTheme();

      }

  }

  
  I'm getting this error with RadExpander when i have that in place. The (few) other controls seem to be fine. Is there a good way of getting design time theme support application wide?

  I finally resolved this by uninstalling the controls and re installing them.

  I'm using version 2011.2.912.40. Project references binaries that are stored in a solution folder, not the ones in the GAC. How Can I fix this error?

  More details:
  Turns out I only get this error when I set the theme to Metro. The application uses Office_Blue globally via StyleManager.ApplicationTheme but I'm overriding it in certain areas of my application using StyleManager.Theme attached property. I can pick any theme but the Metro theme. And I've only encountered this error on the Expander.

  Hi Rayne,

   Could you please elaborate more on your scenario, especially what types of controls do you use? We tried to isolate this issue in a sample project but we did not succeed as you can see in the attached project. Is it possible for you to open a new support ticket with a project attached so that we would be able to investigate it locally ? Thank you in advance.

  All the best,

  I was able to reproduce the problem in a sample application using the dlls my project references. Then I upgraded the sample project to the latest version that I have downloaded (2011.3.1129.40) and it works as expected. So maybe there is a problem with the version of the controls I'm using. When possible, I will update my project dlls and test again.
