Raising an event invokes the event handler through a delegate.
The OnAfterSelectedHolidaysChange 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 OnAfterSelectedHolidaysChange in a derived class, be sure to call the base class's OnAfterSelectedHolidaysChange method so that registered delegates receive the event.
