Comments

The OnItemCollapsed method raises the ItemCollapsed event.

Raising an event invokes the event handler through a delegate.

The OnItemCollapsed 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.

When overriding OnItemCollapsed in a derived class, make sure to call the base class's OnItemCollapsed method so that registered delegates receive the event.
