    In a UserControl, setting up the following causes the RadDiagram to crash when the Connectors are clicked when running
    <Grid x:Name="LayoutRoot" Background="White">
      <telerik:RadDiagram >
        <telerik:RadDiagramShape />

    In the code behind
    namespace SilverlightApplication1.Classes
        public partial class Test : UserControl
            public Test()
                this.LayoutRoot.DataContext = this;
                //Comment out the line above to resolve the issue

    Please could you let me know if there is something incorrect, with the changing of the datacontext,
    or if there is something that I should be doing instead?

    I am using version 2012.1.507.1050 of the assemblies.
    When the application is running, click any of the connector nodes.
    The application crashes with :
        Exception has been thrown by the target of an invocation.
            {System.ArgumentException: Value does not fall within the expected range.
