This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Provides handling for the LostFocus event.

Namespace:  System.Windows.Controls
Assembly:  System.Windows (in System.Windows.dll)

'Declaration
Protected Overrides Sub OnLostFocus ( _
	e As RoutedEventArgs _
)

Parameters

e
Type: System.Windows.RoutedEventArgs
The event data.

This implementation updates the appearance of the control when it loses focus. Do not rely on this method to report when the control loses focus.

The OnLostFocus method is called before any event handler for the LostFocus event is called. This method allows derived classes to handle the LostFocus event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnLostFocus in a derived class, be sure to call the base class’s OnLostFocus method so that registered delegates receive the event.
