{
  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);
    }
  }
}

Private Sub CaptureMouseCommandExecuted(ByVal sender As Object, ByVal e As ExecutedRoutedEventArgs)
  MessageBox.Show("Mouse Command")
  Dim target As IInputElement = Mouse.DirectlyOver

  target = TryCast(target, Control)
  If target IsNot Nothing Then
    If Not target.IsMouseCaptured Then
      Mouse.Capture(target)
    Else
      Mouse.Capture(Nothing)
    End If
  End If
