Provides class handling for the LostFocus event.
Assembly: System.Windows (in System.Windows.dll)
'Declaration Protected Overrides Sub OnLostFocus ( _ e As RoutedEventArgs _ )
protected override void OnLostFocus( RoutedEventArgs e )
This implementation sets the IsFocused property to true.
The OnLostFocus method also allows derived classes to handle the 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, make sure to call the base class’s OnLostFocus method so that registered delegates receive the event.
