Description

Overrides the inherited method to respond to opRemove notifications on the DataSource.

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

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

Note: Notification is a protected method. Applications can't call it directly.
