Set TopLeft cell position or ScrollBar position

I'm using TAdvStringGrid on Delphi10.
How to change the TopLeft cell position? or ...How to change the ScrollBar position ? 
I want to move the scrollbar (or TopLeft cell position) by code.

Best regards,

With grid.TopRow: integer or grid.LeftCol: integer you can programmatically control the scroll position in the grid.

I got it. Thank you, you've been so helpful.

Please tell me one more thing.
Is there a way to get the BottomRow and RightCol?

This is grid.TopRow + grid.VisibleRowCount and grid.LeftCol + grid.VisibleColCount respectively

Oh I see. Thank you, you've been so helpful.
