Represents a method that will handle events that require a node as the parameter.
public delegate void NodeEventHandler( object sender, NodeEventArgs e );
Public Delegate Sub NodeEventHandler( sender As Object, e As NodeEventArgs )
The sender of an event.
A NodeEventArgs object that contains event related data.
When you create a NodeEventHandler delegate, you identify the method that will handle an event. To associate an 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.
