Description

Responds to notifications that components are being created or destroyed.

After calling the inherited class' method, Notification checks whether the notification indicates the removal of DataSource or ListSource. If so, Notification sets the property to nil (Delphi) or NULL (C++).

Derived classes can override Notification method to handle additional notifications, but the inherited class' method should be always be called.
