How to do automatic scroll to show selected row

I have a gird having 100 rows, where only 20 are visible, I have to select any row (say 51st) dynamically , I can do that, but I need to put scrollbar programitically in such a way that 51st row should be visible in the grid.
Any suggestions. I'm using AW.UI.Grid.
