event ImageMapEventHandler^ Click {
	void add(ImageMapEventHandler^ value);
	void remove(ImageMapEventHandler^ value);
}

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.

To programmatically control the actions performed when a postback HotSpot is clicked, provide an event handler for the Click event that contains the code to run when the event is raised.

Raising an event invokes the event handler through a delegate. For more information about handling events, see NIB: Consuming Events.

The following code example demonstrates how to create an ImageMap control that contains two RectangleHotSpot objects. The ImageMap::HotSpotMode property is set to HotSpotMode.PostBack, which causes the page to post back to the server each time a user clicks one of the hot spot regions. The VoteMap_Clicked event handler handles the click event for the ImageMap control. For this example to work correctly, you must supply your own image for the ImageUrl property and update the path to the image appropriately so that the application can locate it.
