| This
property is used to access the row number that is
currently displayed at the top of the Grid. It can be
used to determine/control vertical scrolling of the data. If set, it must be set to a value
between 1 and the number of rows in the Grid.
Setting this property to a
row near the bottom of the Grid contents does not always
guarantee that the row identified will be the first row
on the Grid. The system will attempt to leave the bottom
few rows visible, however it will assure that the row
indicated is visible.
