Свободно проверка, работая в создании, но не редактировать ⇐ C#

[Anonymous]

создание и редактирование видов Используйте один и тот же контроллер проверки. Создайте работы правильно, отображая сообщения об ошибках и сохраняет при исправлении любых проблем проверки, обращаясь к представлению индекса. Однако, когда я использую return View (поправка); , сообщения об ошибках показывают и после исправления, и я нажимаю на сохранение, страница обновляется, а не возвращается на страницу индекса. Это, однако, сохраняет изменения. Вот код контроллера (за исключением деталей и удаления деталей): < /p>
