Delphi-Quellcode:

procedure TForm1.Button1Click(Sender: TObject);
begin
Stringgrid1.Cells[2,2]:='abc'+#10#13+'def';
end;

procedure TForm1.StringGrid1DrawCell(Sender: TObject; ACol, ARow: Integer;
  Rect: TRect; State: TGridDrawState);
var
  S: String;
  drawrect :trect;
begin
  S:= (Sender As TStringgrid).Cells[ ACol, ARow ];
  If Length(S) > 0 Then Begin
    drawrect := rect;
    DrawText((Sender As TStringgrid).canvas.handle,
              Pchar(S), Length(S), drawrect,
              dt_calcrect or dt_wordbreak or dt_left );
    If (drawrect.bottom - drawrect.top) >
       (Sender As TStringgrid).RowHeights[Arow]
    Then
      (Sender As TStringgrid).RowHeights[Arow] :=
         (drawrect.bottom - drawrect.top)
    Else Begin
      drawrect.Right := rect.right;
      (Sender As TStringgrid).canvas.fillrect( drawrect );
      DrawText((Sender As TStringgrid).canvas.handle,
                Pchar(S), Length(S), drawrect,
                dt_wordbreak or dt_left);
    End;
  End;
end;
