Assembly: System.Web (in system.web.dll)
The Click event is raised when a HotSpot object in an ImageMap control is clicked. To allow a HotSpot to raise the Click event, you must first set either the HotSpotMode property on the ImageMap control or the HotSpotMode property on the HotSpot object to HotSpotMode.Postback.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnClick 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 OnClick in a derived class, be sure to call the base class's OnClick method so that registered delegates receive the event.
