The following example copies the selected rows in a db grid
to a list box.  Set the db grid Options dgRowSelect,
dgAlwaysShowSelection and dgMultiSelect to True.  Make a
multiple selecton using the CNTL key.  This example requires
a TDataSet associated with a TDataSource and a TDBGrid.}

var
  i, j: Integer;
  s: string;
begin
  if DBGrid2.SelectedRows.Count>0 then
    with DBGrid2.DataSource.DataSet do
      for i:=0 to DBGrid2.SelectedRows.Count-1 do
      begin
        GotoBookmark(DBGrid2.SelectedRows.Items[i]);
        for j := 0 to FieldCount-1 do
        begin
          if (j>0) then s:=s+', ';
          s := s + FindField(Fields.Fields[j].FieldName).AsString;
        end;
        Listbox1.Items.Add(s);
