public MouseButton ChangedButton { get; }
Members of this class are either not typically used in XAML, or cannot be used in XAML.

Property Value

Type: System.Windows.Input.MouseButton
The button which was pressed.

The Mouse class provides additional properties and methods for determining the state of the mouse.

The following example creates a mouse button event handler that changes the color of an object depending on the mouse button which was pressed. The ChangedButton property is checked to determine which button was pressed.

private void MouseButtonDownHandler(object sender, MouseButtonEventArgs e)
{
    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;
        }
    }
}
