Working with multiselect grids

Delphi 2.0 multiselect grids have an undocumented SelectedRows property, a TBookmark list.
You can use it with a code like this:

With DbGrid1 do begin

  for i := 0 to Pred(SelectedRows.Count) do begin

    DataSource.DataSet.Bookmark := SelectedRows[i];

    {the dataset is positioned on the selection. Do your stuff}

  end;

end;
