MouseButtonEventArgs Class

Provides data for mouse button related events.

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

public class MouseButtonEventArgs extends MouseEventArgs
You cannot directly create an instance of this class in XAML.

MouseButtonEventArgs is used with the following events: MouseDown, MouseUp, MouseLeftButtonDown, MouseLeftButtonUp, MouseRightButtonDown, MouseRightButtonUp, and the corresponding tunneling events.

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 the object that raised the event. The color chosen depends 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;
        }
    }
}
