Заметки
С помощью набора элементов управления веб-частей можно разрешить создание связи между двумя серверными элементами управления для совместного использования данных. При этом один из элементов управления выступает в роли поставщика данных, а другой — в роли получателя. Оба элемента могут иметь тип WebPart или любой другой тип серверного элемента управления при условии, что они предназначены для работы со связями и располагаются в зоне WebPartZoneBase.
Дополнительные сведения об элементе ConnectionsZone и элементах управления веб-частей см. в разделе Элементы управления веб-частей ASP.NET.
Пример
В следующем примере кода демонстрируется декларативное использование элемента управления ConnectionsZone на веб-странице. Для элемента ряд свойств устанавливается декларативно. Другие свойства зоны соединений устанавливаются программно в разделе script страницы.
Определения пользовательских элементов управления, которые определяются с помощью директив @ Register, см. в разделе "Пример" в общих сведениях о классе ConnectionsZone.
