Provides handling for the LostFocus event.
Assembly: System.Windows (in System.Windows.dll)
This implementation updates the appearance of the ListBoxItem when it loses focus.
The 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 in a derived class, make sure to call the base class’s method so that registered delegates receive the event.
