I'm using a StringGrid to display some strings. I don't want the user to alter the values. However I see one cell with the color of the selection (?). My question is. How can I make all the cells look the same (clWhite). When I move focus to the StringGrid the selected colored cell changes to a dotted square with the same color as all the other cells. Hope I don't have to use tricks like OnDrawCell.

Hello Zif,

I don't want to use external components for reasons of maintenance. So I guess I'll have to use the OnDrawCell-event. Can you or someone else give me an example of how to write such an event. I've tried something myself but I'm not yet satisfied with the result and not sure of all the possibilities.

Regards,
The Temple.

Hi detempel, here is the code for ondraw-event

procedure TForm1.StringGrid1DrawCell(Sender: TObject; Col, Row: Integer;
  Rect: TRect; State: TGridDrawState);
const
  LM = 3; {each indiviual cell's left margin}
  TM = 2; {each indiviual cell's top margin}
begin
  if gdFixed in State then {draw fixed columns , fixed}
     (sender as TStringGrid).Canvas.Brush.Color :=
       (sender as TStringGrid).FixedColor;
  if (gdSelected in State) then {draw selected cell , normal}
    begin
      (sender as TStringGrid).Canvas.Brush.Color :=
          (sender as TStringGrid).Color;
      (sender as TStringGrid).Canvas.Font.Color :=
          (sender as TStringGrid).Font.Color;
    end;
  {finally, do the actual cell drawing}
  (sender as TStringGrid).Canvas.TextRect(Rect, Rect.Left + LM, Rect.Top + TM, (sender as TStringGrid).Cells[col,row]);
end;

Regards, Zif.
