Namespace:  System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

'Declaration
Public Event LostKeyboardFocus As KeyboardFocusChangedEventHandler
<object LostKeyboardFocus="KeyboardFocusChangedEventHandler" .../>

Implements

IInputElement.LostKeyboardFocus

Identifier field

LostKeyboardFocusEvent

Routing strategy

Bubbling

Delegate

KeyboardFocusChangedEventHandler

Because this event uses bubbling 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.LostKeyboardFocus attached event for this class, so that LostKeyboardFocus is part of the class members list when UIElement3D is inherited as a base element. Event handlers that are attached to the LostKeyboardFocus event are attached to the underlying Keyboard.LostKeyboardFocus attached event and receive the same event data instance.

LostKeyboardFocus is introduced in the .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.
