Ошибка сетки ExtJs в asp.net mvc

Question

Мне по-прежнему нужна ваша помощь, а точнее реализация сетки ExtJS. Я не могу заставить его работать. У меня есть представление, которое делает поиск с большим количеством параметров, тогда у контроллера будет проведено исследование действий, которое при загрузке страницы я устанавливаю элементы управления последнего, а затем отправляю действие, через которое я выполняю поиск. Это код:

Я проверил отладчик JavaScript и загрузить страницу, когда я вхожу в отладочный ExtJS сетки, даже если я нажимаю кнопку поиска, чтобы поиск назад мне содержание запроса в формате блокнота и я даже не вхожу в javascript debbugger.

Я могу помочь вам понять, почему, я попробовал это с несколькими примерами extjs, но не работает.

Благодаря

Answer 1

сначала вы должны использовать браузер, чтобы убедиться, что ваш asp.net приложение возвращает правильный формат.

Если вы на 100% уверены, что это действительно так, проверьте свой код ExtJs.

Тип общего ответа, но, как сказал Тевс, вы не должны публиковать такой огромный кусок кода.

Также вы могли бы опубликовать xml или json, которые возвращает ваше приложение asp.net, это поможет.

Answer 2

Привет всем и спасибо за ваш ответ, я решил проблему, что я передал ему правильные данные из JSon ExtJS
