private void CaptureMouseCommandExecuted(object sender, ExecutedRoutedEventArgs e)
{
  MessageBox.Show("Mouse Command");
  IInputElement target = Mouse.DirectlyOver;

  target = target as Control;
  if (target != null)
  {
    if (!target.IsMouseCaptured)
    {
      Mouse.Capture(target);
    } else {
      Mouse.Capture(null);
    }
  }
}
