There is, actually, though it's a bit obscure. The PushButton class implements the ActionSource interface, which means that it has an addActionNotificationReceiver method. This method takes, as a parameter, any object that implements the actionNotificationReceiver interface. So you can: 1. Create a class that has "actionNotificationReceiver" among its interfaces. Such a class will therefore have a PerformAction method. 2. On your new pushbutton (let's call it pb), add an instance of your class (let's call it thing) like so: pb.addActionNotificationReceiver thing 3. There's no step three! Now, whenever somebody clicks the pb button, thing's PerformAction method will be called. This isn't necessarily the best way to solve your real problem (another way would be to keep a dictionary that maps pushbuttons to some sort of action, and simply look 'me' up in the button's Action event and act accordingly), but it certainly is a nifty bit of RB trivia, wouldn't you say?
