It looked to me useful to have persistent selection where you can browse with
mouse or keyboard to other section of dataset. Because SelectedRows if public
it just need a dbgrid.SelectedRows.Clear operation after processing the
selected rows. But I think we can make this delphi compatible if you or
somebody provides a spec for this feature.
