Runtime exception generated when no handler subscribed to an event

Question

Hello, I have a user control which generates 2 events e.g. ItemSelected, ItemDoubleClicked. When I create the user control in code and do not add a handler to one of the events, when the event fires I get "Object reference not set to an instance of an object." I am doing something wrong here? I assume I do not have to handle every event fired by my user control? Many thanks, Gary
