Answer 6

都是大同小异阿，察看DELPHI关于DBGRID的SELECTROWS属性的帮助，其中有例子
procedure TForm1.Button1Click(Sender: TObject);
var
  i, j: Integer;
  s: string;
begin
  if DBGrid1.SelectedRows.Count>0 then
    with DBGrid1.DataSource.DataSet do
      for i:=0 to DBGrid1.SelectedRows.Count-1 do
      begin
        GotoBook(pointer(DBGrid1.SelectedRows.Items[i]));
        for j := 0 to FieldCount-1 do
        begin          if (j>0) then s:=s+', ';
          s:=s+Fields[j].AsString;
        end;
        Listbox1.Items.Add(s);
        s:= '';
      end;
end;
