Remarks

Raising an event invokes the event handler through a delegate.

The OnLoadingThumbnailChanged 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 OnLoadingThumbnailChanged in a derived class, be sure to call the base class's OnLoadingThumbnailChanged method so that registered delegates receive the event.

Requirements
