MouseButtonEventHandler Delegate

Represents the method that will handle mouse button related routed events, for example UIElement.MouseLeftButtonDown.

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

type MouseButtonEventHandler = 
    delegate of  
        sender:Object * 
        e:MouseButtonEventArgs -> unit

Parameters

sender
Type: System.Object

The object where the event handler is attached.

e
Type: System.Windows.Input.MouseButtonEventArgs

The event data.

This delegate is used with the following attached events.

This delegate is used with the following routed events. These routed events forward the previously listed attached events to make them more accessible to the general element model in WPF.

The attached events and the base element routed events share their event data, and the bubbling and tunneling versions of the routed events also share event data. This can affect the handled characteristics of the event as it travels the event route. For details, see Input Overview.

The following example creates a MouseDown event handler that changes the background color of the source of the event. The background color is determined by which button is pressed.
