Called before the LostFocus event occurs.
Assembly: System.Windows (in System.Windows.dll)
'Declaration Protected Overrides Sub OnLostFocus ( _ e As RoutedEventArgs _ )
protected override void OnLostFocus( RoutedEventArgs e )
The data for the event.
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 the OnLostFocus method in a derived class, be sure to call the base class’s OnLostFocus method so that registered delegates receive the event.
