What you need to do is store the recno() to a form property in the Afterrowchange event. In the init of the grid class add the following:

with this

.SETALL('DYNAMICBACKCOLOR', 'IIF(RECNO() = THIS.CurRecNo, RGB(0,0,128), RGB(255,255,255))', 'COLUMN')
.SETALL('DYNAMICFORECOLOR', 'IIF(RECNO() = THIS.CurRecNo, RGB(255,255,255), RGB(0,0,0))', 'COLUMN')

endwith

You'll have to adjust it to suite your requirements, but you get the picture.
