Stringgrid sortieren

[bl3nder]

Also habs jetzt so gelöst:

Delphi-Quellcode:

//global
NextTimeSort := 'asc';
SpalteZuletzt := 0;

// sort ascending
function StringListSortCompareAsc(List: TStringList; Index1, Index2: Integer): Integer;
begin
  Result := -AnsiCompareText(List[Index2], List[Index1]);

end;


// sort descending
function StringListSortCompareDesc(List: TStringList; Index1, Index2: Integer): Integer;
begin
  Result := AnsiCompareText(List[Index2], List[Index1]);

end;


procedure TForm1.SortStringGrid(var GenStrGrid: TStringGrid; ThatCol: Integer);
const
  // Define the Separator
  TheSeparator = '@';
var
  CountItem, I, J, K, ThePosition: integer;
  MyList: TStringList;
  MyString, TempString: string;
begin
  // Give the number of rows in the StringGrid
  CountItem := GenStrGrid.RowCount;
  //Create the List
  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);
      //Sort the List
      if (spalteZuletzt <> ThatCol) OR ((spalteZuletzt = ThatCol) AND (NextTimeSort = 'asc')) then
      begin
        Mylist.CustomSort(StringListSortCompareAsc);
        NextTimeSort := 'desc';
      end
      else if ((spalteZuletzt = ThatCol) AND (NextTimeSort = 'desc')) then
      begin
        Mylist.CustomSort(StringListSortCompareDesc);
        NextTimeSort := 'asc';
      end;



      for K := 1 to Mylist.Count do
      begin
        //Take the String of the line (K – 1)
        MyString := MyList.Strings[(K - 1)];
        //Find the position of the Separator in the String
        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;

      // Refill the StringGrid
      for J := 1 to (CountItem - 1) do
        GenStrGrid.Rows[J].Text := MyList.Strings[(J - 1)];
    end;
  finally
    //Free the List
    MyList.Free;
  end;

  spalteZuletzt := ThatCol;
end;


procedure TForm1.GridMouseDown(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
Var
  i,breite,spalte:Integer;
begin
if y<=Grid.RowHeights[0] then
begin
  breite:=0;
  For i:=0 To Grid.ColCount-1 Do
  Begin
    breite:=breite+Grid.ColWidths[i];
    if breite>x Then
    Begin
      spalte:=i;
      Break;
    end;
  end;
  SortStringGrid(Grid, spalte);
end;
end;
