When you create a BulletedListEventHandler delegate, you identify the method that will handle the Click event of a BulletedList control. 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 example demonstrates how to specify and code an event handler for the Click event of a BulletedList control. When a list item is clicked, a message is displayed in a Label control on the page.
