Note

Il controllo DetailsView consente di visualizzare un singolo record di un'origine dati in una tabella, in cui ogni campo del record è visualizzato in una riga. Può essere utilizzato insieme a un controllo GridView per scenari Master-Details.

L'oggetto DynamicField è un nuovo campo introdotto in .NET Framework 3.5 SP1. Può essere utilizzato da un controllo DetailsView nelle applicazioni ASP.NET Dynamic Data. Per ulteriori informazioni su Dynamic Data, vedere Cenni preliminari su ASP.NET Dynamic Data.

Esempio

Nell'esempio di codice riportato di seguito viene illustrato come utilizzare un controllo DetailsView insieme a un controllo GridView per un semplice scenario Master-Details. Vengono visualizzati i dettagli di un elemento selezionato nel controllo GridView.

Per ulteriori informazioni sull'utilizzo del controllo DetailsView, vedere Informazioni generali sul controllo server Web DetailsView.
