Commenti

La riga del piè di pagina viene visualizzata nella parte inferiore del FormView controllo quando viene impostata la FooterText proprietà o FooterTemplate . Utilizzare la FooterRow proprietà per accedere a livello di codice all'oggetto FormViewRow che rappresenta la riga del piè di pagina.

Nota

La FooterRow proprietà è disponibile solo dopo che il FormView controllo crea la riga del piè di pagina nell'evento ItemCreated .

Questa proprietà viene comunemente usata quando è necessario modificare a livello di codice la riga del piè di pagina, ad esempio quando si aggiunge contenuto personalizzato. Tutte le modifiche apportate alla FooterRow proprietà devono essere eseguite dopo il rendering del FormView controllo. In caso contrario, il FormView controllo sovrascrive eventuali modifiche.

Per controllare lo stile della riga del piè di pagina, utilizzare la FooterStyle proprietà .
