{
    Control src = e.Source as Control;

    if (src != null)
    {
        switch (e.ChangedButton)
        {
            case MouseButton.Left:
                src.Background = Brushes.Green;
                break;
            case MouseButton.Middle:
                src.Background = Brushes.Red;
                break;
            case MouseButton.Right:
                src.Background = Brushes.Yellow;
                break;
            case MouseButton.XButton1:
                src.Background = Brushes.Brown;
                break;
            case MouseButton.XButton2:
                src.Background = Brushes.Purple;
                break;
            default:
                break;
        }
