This property returns the position of the top of the current cell.
object.CellTop [= number]
The CellTop property is unavailable at design time and read-only at run time.
This property is useful if you want to emulate in-cell editing. By trapping the KeyPress event of the Grid control, you can place a text box or some other control over the current cell and let the user edit its contents.
The return values are always in twips, regardless of the form's ScaleMode setting.
