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

They're Your own events I think. Use them like this: if(myEventHandler!=null) myEventHandler(thismyEventArgs);

It's because there's nothing attached to the event which for some reason causes a null reference exception. You might try attaching a function that does nothing.
