Description

Sets the event handler for the num box user control that is specified by userControlID.

Event handlers are simply scripts to be called when certain events happen. User controls get notified about changes in state when users interact with them. Each event handler flag takes as an argument: a script (which must reside in your script directories).

To clear an event handler, pass the empty string, "", to the flag. If no options are specified, all handlers are reset, and the user control will not respond to any events.
