KeyboardFocusChangedEventHandler Delegate


Represents the method that will handle the UIElement.LostKeyboardFocus and UIElement.GotKeyboardFocus routed events, as well as related attached and Preview events.

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

public delegate void KeyboardFocusChangedEventHandler(
	object sender,
	KeyboardFocusChangedEventArgs e


Type: System.Object

The object where the event handler is attached.

Type: System.Windows.Input.KeyboardFocusChangedEventArgs

The event data.

This delegate is used with the following attached events:

This delegate is also used with the following routed events on base elements. 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.

If the PreviewGotKeyboardFocus event or the PreviewLostKeyboardFocus event is handled (Handled is set to true in the event data), keyboard focus will not change.
