I did not found property to know the rownumber of a TDBGrid,
so I will try this in the OnDrawColumnCell of a DBGrid:
}
procedure TformX.DBGridXDrawColumnCell(Sender: TObject; const Rect: TRect; DataCol: Integer; Column: TColumn; State: TGridDrawState); var RowNo : Integer; begin RowNo := Rect.Bottom div TStringGrid(DBGridX).DefaultRowHeight //so, RowNo has the Row to be draw in the moment ... end;
