    Hi Tolga,

    Try opening RadWindow in the Page.Loaded event, instead of the page constructor. This usually fixes the problem:

    public partial class SilverlightControl1 : UserControl
    {
     public SilverlightControl1()
     {
      InitializeComponent();

      this.Loaded += new RoutedEventHandler(SilverlightControl1_Loaded);
      // window1.Show();
     }

     void SilverlightControl1_Loaded(object sender, RoutedEventArgs e)
     {
      window1.Show();
     }
    }



    If this does not help, please, open a new support ticket and send us a simple application that can be used to reproduce the problem and we will respond with a solution as soon as possible.

    I have the same error, when I try to open a RadWindow with a usercontrol

    on the Page I load a user control with a button, the button will open a RadWindow with
    a usercontrol that contains a combobox.
    When the window is opened and I click the combobox the error occurs

    I'm using the latest version of the silverlight controls

    David.
