Provides handling for the LostFocus event.
protected override void OnLostFocus(
This implementation updates the appearance of the ListBoxItem when it loses focus.
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.
