MouseButton Enumeration

.NET Framework 4.5

Defines values that specify the buttons on a mouse device.

Namespace: System.Windows.Input
Assembly: PresentationCore (in PresentationCore.dll)

public enum MouseButton

XAML Attribute Usage

<object property="enumerationMemberName" .../>

	Member name	Description
	Left	The left mouse button.
	Middle	The middle mouse button.
	Right	The right mouse button.
	XButton1	The first extended mouse button.
	XButton2	The second extended mouse button.

The following example creates a MouseDown event handler that uses the MouseButton enumeration to determine which button was pressed. Depending on which button was pressed, the background of the control that fired the event is changed.

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;
        }
    }
}
