When ClearSelection, SelectedRow still keep its value, which was not what we want: set it to -1

HI

When Call AddChindRow with crLast, the component makes some order error, sometimes it doesn't add the row at last, but any random place.

I make a little bit change of the Tree demo program, only add an integer to the cell text, like this:

procedure TForm2.Button2Click(Sender: TObject);

begin

if CheckBox2.Checked

then NextGrid1.AddChildRow(NextGrid1.SelectedRow, crLast)

else NextGrid1.AddChildRow(NextGrid1.SelectedRow, crFirst);

Count := Count + 1;

NextGrid1.Cell[2, NextGrid1.LastAddedRow].AsString := 'Child Row'+IntToStr(Count);

NextGrid1.Cell[3, NextGrid1.LastAddedRow].AsInteger := Random(100);

end;

after you adding a few rows and childrows into it, error will be coming.
