Hi,
I guess he is asking about somehting else
Normally, clicking the button is referred to as an 'Event' and functions that produce result of an event are called as 'Event Handlers'. When an event occurs, all the event handler fuctions are invoke. To invoke all these functions when an event is triggered, the event should know what all functions are associated with it. The c# way of executing a method is using a machanism called event delegate. you can simply take it as a method pointer.
eg:- this.menuItemGoto.Click += new System.EventHandler(this.menuItemGoto_Click);
