У меня есть вложенное GridView. Когда строка данных в этой вложенной сетке находится в режиме редактирования, я хотел бы, чтобы 2 из столбцов менялись на выбранные выпадающие списки. Когда пользователь делает выбор в первом выпадающем списке, список во втором раскрывающемся списке меняется. Это делается на стороне клиента, используя jquery. Этот проект хорошо работает в другой сетке в приложении, это НЕ Вложенная сетка.выбрали выпадающая функция изменения не вызывает в гнездовом GridView
Проблема заключается в том, что сначала выпадающих созданы, но не отображаются в выбранных выпадающих стиле. Затем, когда пользователь меняет значение в первом выпадающем списке, событие изменения не запускается, а второй раскрывающийся список не обновляется. Однако, если вы выберете значение во втором выпадающем меню, оба элемента управления изменятся на выбранный стиль.
Это моя разметка:

Таким образом, чтобы подтвердить ... выбранный стиль не создается, когда сеть находится в режиме редактирования и «изменение» событие JQuery не запускается выпадающего меню DEVICENAME.
Может кто-нибудь увидеть, где я неправильно?
Спасибо.
UPDATE я понял, часть моей проблемы ... раскрывающийся на DeviceName не имеют атрибут Autopostback=true. Это привело к тому, что функция готовности документа активировала и обновила раскрывающееся меню ServiceName.
Однако теперь, когда ИмяУстройства выпадающий меняется, она закрывает вложенную GridView. После изменения сетка должна оставаться открытой.
