UIElement.PreviewLostKeyboardFocus Event

Definition

Occurs when the keyboard is no longer focused on this element.

C#
public event System.Windows.Input.KeyboardFocusChangedEventHandler PreviewLostKeyboardFocus;

Event Type

Implements

Remarks

Because this event uses tunneling routing, the element that lost focus might be a child element instead of the element where the event handler is actually attached. Check the Source in the event data to determine the actual element that lost focus.

This event creates an alias for the Keyboard.PreviewLostKeyboardFocus attached event for this class, so that PreviewLostKeyboardFocus is part of the class members list when UIElement is inherited as a base element. Event handlers that are attached to the PreviewLostKeyboardFocus event are attached to the underlying Keyboard.PreviewLostKeyboardFocus attached event and receive the same event data instance.
