Identifying the signature for an event handler on an OpenEdge .NET object
To identify the signature required for any ABL method or procedure that you want to define as a handler for a .NET event on an OpenEdge .NET object:
1. Look up the object event that you want to handle in the OpenEdge documentation for the event (see the Class Events Reference section of OpenEdge Development: ABL Reference).
2. The syntax that introduces the event reference entry shows the required signature. For example, in the reference entry for the CreateRow event, this syntax appears:
EventHandlerName (INPUT sender AS CLASS System.Object,
INPUT args AS CLASS Progress.Data.CreateRowEventArgs).
3. You can then define your event handler parameter accordingly.
