DetailsView Элемент управления CommandFieldвызывает событие при щелчке кнопки в поле строки TemplateField ,или.ButtonField ItemCommandThe DetailsView control raises the ItemCommand event when a button within a ButtonField, CommandField, or TemplateField row field is clicked. Это позволяет предоставить обработчик событий, который выполняет пользовательскую подпрограммы при возникновении этого события.This allows you to provide an event handler that performs a custom routine whenever this event occurs.

Примечание

Элемент управления также вызывает другие специализированные события при нажатии определенных кнопок (кнопки CommandName со свойством, для которых задано значение "Удалить", "вставить", "страница" или "Обновить"). DetailsViewThe DetailsView control also raises other specialized events when certain buttons are clicked (buttons with the CommandName property set to "Delete", "Insert", "Page", or "Update"). При использовании одной из этих кнопок следует рассмотреть возможность использования одного из специализированных событий, предоставляемых элементом управления (например ItemDeleted , или ItemDeleting).When using one of these buttons, you should consider using one of the specialized events provided by the control (such as ItemDeleted or ItemDeleting).

При создании делегата DetailsViewCommandEventHandler необходимо указать метод, обрабатывающий событие.When you create a DetailsViewCommandEventHandler delegate, you identify the method that will handle the event. Чтобы связать событие с обработчиком событий, нужно добавить в событие экземпляр делегата.To associate the event with your event handler, add an instance of the delegate to the event. Обработчик событий вызывается всякий раз, когда происходит событие, если делегат не удален.The event handler is called whenever the event occurs, unless you remove the delegate. Дополнительные сведения о делегатах обработчиков событий см. в разделе обработка и вызов событий.For more information about event-handler delegates, see Handling and Raising Events.
