Sort fine, but in my stringgrid i've got even empty spaces. When I sort the stringgrid the empty rows become before the data from my text.
ex:

a a a a a
b b b b b
'' ''  ''  '' ''

''-empty cell.....means that i've got an empty row.

after sort... the empty row is the first as normaly...but how can I prevent that and put the empty spaces last?
Thanks.

I forgot to show the code:

procedure SortStringGrid(var GenStrGrid: TStringGrid; ThatCol: Integer);
const
  TheSeparator = '@';
var
  CountItem, I, J, K, ThePosition: integer;
  MyList: TStringList;
  MyString, TempString: string;
begin
  CountItem := GenStrGrid.RowCount;
  MyList        := TStringList.Create;
  MyList.Sorted := False;
  try
    begin
      for I := 1 to (CountItem - 1) do
        MyList.Add(GenStrGrid.Rows[I].Strings[ThatCol] + TheSeparator +
          GenStrGrid.Rows[I].Text);
      Mylist.Sort;
      for K := 1 to Mylist.Count do
      begin
        MyString := MyList.Strings[(K - 1)];
        ThePosition := Pos(TheSeparator, MyString);
        TempString  := '';
        {Eliminate the Text of the column on which we have sorted the StringGrid}
        TempString := Copy(MyString, (ThePosition + 1), Length(MyString));
        MyList.Strings[(K - 1)] := '';
        MyList.Strings[(K - 1)] := TempString;
      end;
      for J := 1 to (CountItem - 1) do
        GenStrGrid.Rows[J].Text := MyList.Strings[(J - 1)];
    end;
  finally
    MyList.Free;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  SortStringGrid(StringGrid1, 1);
end;
