Привет, я закончил создание сетки, добавляю, редактирую, обновляю выпадающие списки из внутренних таблиц соединения.Все работает только в редактировании, восстанавливает выпадающие списки до их первых значений, и я хочу, чтобы когда пользователь нажимал, чтобы редактировать, чтобы показать имя добавленной стоимости, заранее спасибо. Это мой код:
