Sintassi dichiarativa per il controllo server Web ConnectionsZone
[Questa documentazione ha solo scopo di anteprima ed è soggetta a modifiche nelle versioni successive. Gli argomenti vuoti sono inclusi come segnaposto.]
Fornisce un'interfaccia utente che consente agli utenti di creare connessioni tra il controllo WebPart e altri controlli server che risiedono in zone WebPartZoneBase.

Note
Utilizzando il set di controlli Web part, è possibile consentire a due controlli server di creare una connessione e condividere i dati, con uno dei controlli che funge da provider e l'altro da consumer dei dati. I due controlli possono essere controlli WebPart o qualsiasi altro tipo di controllo server, ammesso che siano progettati per gestire le connessioni e risiedano in una zona WebPartZoneBase.
Per ulteriori informazioni sul controllo ConnectionsZone e sui controlli Web part, vedere ASP.NET Web Parts Pages.
Esempio
Nell'esempio di codice riportato di seguito viene illustrato come utilizzare in modo dichiarativo il controllo ConnectionsZone in una pagina Web. All'interno dell'elemento diverse proprietà vengono impostate in modo dichiarativo. Altre proprietà nella zona delle connessioni vengono impostate a livello di codice nella sezione script della pagina.
Per le definizioni del controllo utente e del controllo personalizzato definito con le direttive @ Register, vedere l'esempio riportato nei cenni preliminari sulla classe ConnectionsZone.
