'Declaration Public Property ActiveRowScrollRegion As RowScrollRegion
public RowScrollRegion ActiveRowScrollRegion {get; set;}
Use the ActiveRowScrollRegion property to determine which RowScrollRegion object is currently active. If you assign an RowScrollRegion object to the ActiveRowScrollRegion property, it will become the active row scrolling region.
Only one row scrolling region at a time may be the active RowScrollRegion. The active RowScrollRegion is the one that contains the active row (as specified by the ActiveRow property). It is also the row scroll region that receives keyboard navigation focus. For example, if you use the up and down arrow keys to scroll rows, the rows in the row scrolling region specified by ActiveRowScrollRegion are the ones that will move.
