Kommentarer

Sidfotsraden visas längst ned i DetailsView kontrollen när FooterText egenskapen eller FooterTemplate har angetts. Använd egenskapen FooterRow för att programmatiskt komma åt objektet DetailsViewRow som representerar sidfotsraden.

Note

Egenskapen FooterRow är endast tillgänglig när DetailsView kontrollen skapar sidfotsraden ItemCreated i händelsen.

Den här egenskapen används ofta när du behöver ändra sidfotsraden programmatiskt, till exempel när du lägger till anpassat innehåll. Alla ändringar av egenskapen FooterRow måste utföras efter att DetailsView kontrollen har renderats. Annars DetailsView skriver kontrollen över eventuella ändringar.

Om du vill styra sidfotsradens format använder du FooterStyle egenskapen .
