Я хочу обновить свои записи, используя подробные представления.Все работает лучше, чем выпадающий список в шаблоне edititem.
Когда я выбираю значение из выпадающего списка (связанного с другой таблицей), я получаю сообщение об ошибке System.ArgumentOutOfRangeException: 'DropDownList1'.
Пожалуйста, помогите,Большое спасибо.
