    {
        if(command == MediaCommands.Pause)
        {
               MyPauseMethod();
        }
        if(command == MediaCommands.Play)
        {
               MyPlayMethod();

        }
    }
}

Private Sub ExecutedDisplayCommand(ByVal sender As Object, ByVal e As ExecutedRoutedEventArgs)
    Dim command As RoutedCommand = TryCast(e.Command, RoutedCommand)

    If command IsNot Nothing Then
