Note
Il controllo FormView consente di visualizzare un singolo record di un'origine dati. È simile al controllo DetailsView, con la differenza che visualizza modelli definiti dall'utente anziché campi riga. Per la visualizzazione, la modifica e l'aggiornamento dei record è possibile assegnare diversi modelli definiti dall'utente. La creazione di modelli personalizzati consente di definire con maggiore flessibilità la modalità di visualizzazione dei dati. For more information about the FormView control, see Cenni preliminari sul controllo server Web FormView.
Esempio
Nell'esempio di codice riportato di seguito viene illustrato come utilizzare un controllo FormView per visualizzare i valori di un controllo SqlDataSource.
