Parameters

Remarks

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

The OnItemValueNeeded 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 you override OnItemValueNeeded in a derived class, make sure to call the OnItemValueNeeded method of the base class so that registered delegates receive the event.
