Декларативный синтаксис серверного веб-элемента управления ProxyWebPartManager
Предоставляет разработчикам способ объявления статических соединений на странице содержимого, когда на главной странице, связанной со страницей содержимого, объявлен элемент управления WebPartManager.

Заметки
Элемент управления ProxyWebPartManager существует в определенных случаях объявления статических соединений на странице содержимого, когда на главной странице уже объявлен элемент управления WebPartManager.

Пример
В следующем примере кода показывается использование класса ProxyWebPartManager для объявления статических соединений на странице содержимого в приложении, в котором используются главные страницы.
Определения пользовательских элементов управления, определенных с помощью директив @ Register, а также главная страница, на которую указывает ссылка атрибута MasterPageFile в директиве @ Page, см. в примере в описании класса ProxyWebPartManager.
