У меня есть список радиокнопок с событием selectedindexbound, который обновляет функцию поиска. Один из элементов указан в aspx, а остальные являются присоединенными элементами с привязкой к данным. Независимо от того, что я установил по умолчанию, этот элемент не будет запускать событие. Все остальные предметы будут запускать событие. Кроме того, кажется, что после выбора «мертвого» предмета событие вообще не сработает.
Как я могу отследить ошибку и исправить? Вот текущий код.
РЕДАКТИРОВАТЬ: Извините, если короткая версия вводит в заблуждение. Я не был уверен, что включить. Вот вся страница.
