'Declaration Protected Overridable Sub OnBeforeDisplayReminderDialog( _ ByVal e As CancelableAppointmentEventArgs _ )
protected virtual void OnBeforeDisplayReminderDialog( CancelableAppointmentEventArgs e )
Raising an event invokes the event handler through a delegate.
The OnBeforeDisplayReminderDialog 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 OnBeforeDisplayReminderDialog in a derived class, be sure to call the base class's OnBeforeDisplayReminderDialog method so that registered delegates receive the event.
