Remarks

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnBeginPrint method also enables 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 OnBeginPrint in a derived class, make sure to call the OnBeginPrint method of the base class so that registered delegates receive the event.

.NET Framework Security

• Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.
