    I am newbie in using silverlight and also in rad tileview. I already search for the error that I encountered but failed to make it works.

    I have a sample project that has a class collection that is set to itemsouce of RadTileview Control. 
    Then, I put in the contenttemplate of tileview the usercontrol and expose a property with binding property.
    When running the project, it infinitely loads the usercontrol and if I debug the code, it shows an error with an error "System.ArgumentException: Value does not fall within the expected range." to the Application_UnhandledException of App.xaml.vb.
    If I remove the binding property of my usercontrol to the tileview and replace it with a default value, the project works well.

    Here is my files for anyone could help me.

    Thank you in advance.

    Hello Mark,

     The problem is that NameDisplay is a normal property. In wpf and silverlight in order for a binding to works the target of the binding(in your case NameDisplay) should be a DependencyProperty.
    If you have further questions feel free to ask.
