Leadtools.Windows.Annotations Namespace > AnnObject Class : OnIsHeaderVisibleChanged Method |
Raising an event invokes the event handler through a delegate.
The OnIsHeaderVisibleChanged 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 OnIsHeaderVisibleChanged in a derived class, be sure to call the base class's OnIsHeaderVisibleChanged method so that registered delegates receive the event.
