The BusinessLayer.OnCurrentRowIndexMoved() method makes reference to the CurrentRowIndexMoved event, but the event is unavailable because it's marked with "Friend" access.



Any particular reason this event is "Friend", but all the other events are "Public"?

Yes, this is an internal event that should not be exposed upon pain of death



There is a lot of logic around this and for the purposes of needing access to knowing when the row changes, you should use the Navigated or the Navigating event.
