It seems something obvious to have. I want the texts to be in the center of the cell, but for some reason I can't find it in properties. How can I do this?

+7  A: 

There's no property to center the text in TStringGrid, but you can do that at DrawCell event as:

procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
  Rect: TRect; State: TGridDrawState);
var
  S: string;
  SavedAlign: word;
begin
  if ACol = 1 then begin  // ACol is zero based
    S := StringGrid1.Cells[ACol, ARow]; // cell contents
    SavedAlign := SetTextAlign(StringGrid1.Canvas.Handle, TA_CENTER);
    StringGrid1.Canvas.TextRect(Rect,
      Rect.Left + (Rect.Right - Rect.Left) div 2, Rect.Top + 2, S);
    SetTextAlign(StringGrid1.Canvas.Handle, SavedAlign);
  end;
end;

The code I posted from here

UPDATE:

to center text while writing in the cell, add this code to GetEditText Event:

procedure TForm1.StringGrid1GetEditText(Sender: TObject; ACol, ARow: Integer;
  var Value: string);
var
  S : String;
  I: Integer;
  IE : TInplaceEdit ;
begin
  for I := 0 to StringGrid1.ControlCount - 1 do
    if StringGrid1.Controls[i].ClassName = 'TInplaceEdit' then
    begin
      IE := TInplaceEdit(StringGrid1.Controls[i]);
      ie.Alignment := taCenter
    end;
end;

Thanks. So, if I want it to be centered as the user writes in its cells, then I should do this in onEdit()?

The code above is implemented in the `OnDrawCell` event and should be left there. If you want the the input to be centered as the user center's it, then you should use the editors TEdit/TWhateverEdit's paint events for that.

Flom, I have updated the answer.

Thanks Mohammed. That is a good way to implement it. I was wondering, isn't there a better component for adding/editing data in a table like StringGrid? Because StringGrid is somehow limited in features.
