Vali,
GridHitTest works. How do you code it ? MouseDown object (typically a control in grid.column) gets MouseUp also. ie :

*mdown
LPARAMETERS nButton, nShift, nXCoord, nYCoord
store 0 to nWhere, nRelrow, nRelCol
with This.parent.parent
 .GridHittest(nXCoord, nYCoord, @nWhere, @nRelRow, @nRelCol)
 .tag = transform(nWhere)+transform(nRelRow)+transform(nRelCol)
endwith
*mup
LPARAMETERS nButton, nShift, nXCoord, nYCoord
store 0 to nWhere, nRelrow, nRelCol
with This.parent.parent
 .GridHittest(nXCoord, nYCoord, @nWhere, @nRelRow, @nRelCol)
 .tag = .tag+chr(13)+transform(nWhere)+transform(nRelRow)+transform(nRelCol)
 messagebox(.Tag)
endwith

You could easily find out start and end rows with a little math. However you should control scrolling too.
