In a TAdvStringGrid Convert x,y to Col,Row

Using Delphi XE, Ver 5.8. From the OnMouseDown Event I know the Screen X,Y click pos I can not find a way to tell which cell was clicked on Col,Row. I am sorry for the simple question I have been using Delphi 6 and Top Grid for may years and do not under stand the StringGrid functionality, I am also finding the Delphi XE help system not very helpfull.

Thanks in Advance

Please use:

grid.MouseToCell() to convert mouse X,Y coordinates to cell coordinates.
