: : : how can I give alternate background colors to the rows of a stringgrid?

Sorry Wiona for my vague answer, didn't have the source code at hand, but hope now it's better.

In the Object Inspector, double click the OnDrawCell event of the stringgrid. Delphi creates the skeleton of a procedure, complete it like this:

procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
  Rect: TRect; State: TGridDrawState);
  if (ACol <> 0) and (ARow <> 0) and (Arow mod 2 = 0) then begin
    StringGrid1.Canvas.Brush.Color := clYellow; // or other wanted color
    StringGrid1.Canvas.TextOut(Rect.Left + 2, Rect.Top + 2,
      StringGrid1.Cells[ACol, ARow]);
