Kommentarer
Sidfotsraden visas längst ned i FormView kontrollen när FooterText egenskapen eller FooterTemplate har angetts. Använd egenskapen FooterRow för att programmatiskt komma åt objektet FormViewRow som representerar sidfotsraden.
Note
Egenskapen FooterRow är endast tillgänglig när FormView 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 FormView kontrollen har renderats. Annars FormView skriver kontrollen över eventuella ändringar.
Om du vill styra sidfotsradens format använder du FooterStyle egenskapen .
