    I have a ResourceDictionary xaml file that I use for centralized styling.  In it I'm trying to use the style below but am getting an error:
    Error 1 The type 'telerik:ThemeResourceKey' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built. C:\Development\BestpassEM\WPFInfrastructure\Styles\ControlStyles.xaml 36 65 Miscellaneous Files
    I have the namespace def at the top of my file (xmlns:telerik="" ) what else would I need?

    I did have this working but then had to switch my target framework from 4.0 Client Profile to the full verion of 4.0 (to support the telerik ReportViewer control).  What could that have broken?

    <Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource {telerik:ThemeResourceKey ThemeType=telerik:Windows7Theme, ElementType=TextBox}}" x:Key="EditTextStyle">
      <Setter Property="HorizontalAlignment" Value="Left" />
      <Setter Property="Margin" Value="2" />
      <Setter Property="Foreground" Value="#333333" />
      <!--<Setter Property="Height" Value="22" />
      <Setter Property="BorderBrush" Value="{StaticResource ControlOuterBorder_Normal}" />-->
      <Setter Property="Validation.ErrorTemplate" Value="{StaticResource validationTemplate}"/>
        <Trigger Property="Validation.HasError" Value="True">
          <Setter Property="ToolTip"
          Value="{Binding RelativeSource={RelativeSource Self},

    Hello Heather,

     We apologize for the delayed answer.

    You also need a reference to Telerik.Windows.Controls in your project. Please , check if you have that in your namespace definitions.

    If that does not help, would it be possible for you to send us a sample which we can test for you ?

    Kind regards,

    Now I apologize for the delayed answer...moved onto other things.  Whatever the problem was was resolved by shutting down and re-opening the project.  Visual Studio just seemed to get completely out of whack.  Sorry I forgot to close the problem.
