Комментарии

Строка нижнего колонтитула отображается в нижней части DetailsView элемента управления, когда FooterText свойство или FooterTemplate задано.The footer row is displayed at the bottom of the DetailsView control when the FooterText or FooterTemplate property is set. Используйте FooterRow свойство для программного доступа к DetailsViewRow объекту, представляющему строку нижнего колонтитула.Use the FooterRow property to programmatically access the DetailsViewRow object that represents the footer row.

Примечание

FooterRowСвойство доступно только после того, как DetailsView элемент управления создаст строку нижнего колонтитула в ItemCreated событии.The FooterRow property is available only after the DetailsView control creates the footer row in the ItemCreated event.

Это свойство обычно используется, когда необходимо программно управлять строкой нижнего колонтитула, например при добавлении пользовательского содержимого.This property is commonly used when you need to programmatically manipulate the footer row, for example when adding custom content. Любое изменение FooterRow свойства должно выполняться после DetailsView подготовки элемента управления к просмотру; в противном случае DetailsView элемент управления перезапишет любые изменения.Any modification to the FooterRow property must be performed after the DetailsView control has been rendered; otherwise, the DetailsView control will overwrite any changes.

Чтобы управлять стилем строки нижнего колонтитула, используйте FooterStyle свойство.To control the style of the footer row, use the FooterStyle property.
