How to change the font properties of a certain row or column in a TStringGrid

Answer:

You can do it by handling the OnDrawCell event.

procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
  Rect: TRect; State: TGridDrawState);
begin
  StringGrid1.Canvas.FillRect(Rect);
  if ARow = 1 then {Use ACol for column or use both for a cell}
  begin
    StringGrid1.Canvas.Font.Color := clBlue;
    StringGrid1.Canvas.Font.Name := 'Tahoma';
    StringGrid1.Canvas.Font.Style := StringGrid1.Canvas.Font.Style + [fsBold];
  end;
  DrawText(StringGrid1.Canvas.Handle, PChar(StringGrid1.Cells[ACol, ARow]), -1,
    Rect, DT_SINGLELINE or DT_VCENTER or DT_LEFT);
end;
