Я создаю динамическую ссылку во время page_init и привязываюсь к кнопке ссылки. Щелчок динамической ссылки может отправлять сообщения назад, но не поднимает событие onclick (нажатие на событие click в режим отладки). Page postback и показывает пустую страницу без запуска события. Пожалуйста, кто-нибудь может сказать, что я делаю неправильно в следующем коде. Я использую vs2005 (ASp.Net 2.0). Пожалуйста, посмотрите первый случай переключателя, когда я динамически создаю ссылку.Кнопка динамической ссылки ASP.NET
