Commenti

La riga del piè di pagina viene visualizzata nella parte inferiore del FormView controllo quando viene impostata la FooterText proprietà o FooterTemplate . È possibile definire un'interfaccia utente personalizzata per la riga del piè di pagina usando la FooterTemplate proprietà . Per specificare un modello personalizzato per la riga del piè di pagina, posizionare <FooterTemplate> prima i tag tra i tag di apertura e chiusura del FormView controllo. È quindi possibile elencare il contenuto del modello tra i tag di apertura e chiusura <FooterTemplate> . Per controllare lo stile della riga del piè di pagina, utilizzare la FooterStyle proprietà . In alternativa, è possibile visualizzare semplicemente il testo nella riga del piè di pagina impostando la FooterText proprietà anziché questa proprietà.

Nota

Se vengono impostate entrambe le FooterText proprietà e FooterTemplate , la proprietà ha la FooterTemplate precedenza.
