ApplyRange, VIRTUAL, PROC
The ApplyRange method applies the range limits and calls the ApplyFilter method if the range limits have changed. The ApplyRange method returns a value indicating whether or not a change occurred. A return value of one (1 or True) indicates a change; a return value of zero (0 or False) indicates no change.
The AddRange method specifies the range limits for the ViewManager object. The SetSort method sets the active sort order.
Implementation:
The ApplyRange method applies range limits and filters with the ApplyFilter method.
