ImageMapEventHandler Delegate

Represents the method that handles the Click event of an ImageMap control.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

type ImageMapEventHandler = 
    delegate of 
        sender:Object * 
        e:ImageMapEventArgs -> unit

Parameters

sender
Type: System.Object
The source of the event.
e
Type: System.Web.UI.WebControls.ImageMapEventArgs
The argument of type ImageMapEventArgs that contains the event data.

When you create an ImageMapEventHandler delegate, you identify the method that handles the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates.

The following code example demonstrates how to create an event handler for the Click event. The ImageMap control 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 RectangleHotSpot objects. The Click event is handled by the VoteMap_Clicked event handler. 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.
