Note

Il controllo WebPartZone contiene i controlli WebPart, che costituiscono l'interfaccia utente principale delle applicazioni Web part. Il controllo WebPartZone può essere dichiarato in formato di persistenza in una pagina Web. In tal modo gli sviluppatori possono utilizzarlo come modello, nonché per aggiungere altri controlli server all'interno dell'elemento asp:webpartzone. Qualsiasi tipo di controllo server, se aggiunto a una zona WebPartZone, può fungere da controllo WebPart in fase di esecuzione, indipendentemente dal fatto che si tratti di un controllo WebPart, un controllo utente, un controllo personalizzato o un controllo ASP.NET. Per ulteriori informazioni, vedere GenericWebPart.

Per ulteriori informazioni sul controllo WebPartZone e sui controlli Web part, vedere Controlli Web part ASP.NET.

Esempio

Nell'esempio di codice riportato di seguito viene illustrato come utilizzare in modo dichiarativo il controllo WebPartZone in uno scenario Web part con il controllo Calendar. La pagina Web consente a un utente di passare in modalità di modifica per modificare determinati aspetti del controllo Calendar. Il pulsante Toggle Scope consente di attivare l'ambito di personalizzazione utente o l'ambito di personalizzazione condiviso per la pagina. I pulsanti Edit Mode e Browse Mode consentono di attivare la modalità di visualizzazione appropriata per la pagina. Si noti che nella sezione del tag <script> del file, due dei metodi che gestiscono gli eventi utilizzano la proprietà Personalization per accedere ai membri utili dell'oggetto sottostante. In particolare questi metodi utilizzano il metodo ToggleScope e la proprietà Scope sull'oggetto accessibile tramite la proprietà Personalization.

Per poter eseguire l'esempio di codice, è inoltre necessario consentire a uno o più utenti di personalizzare le pagine nell'ambito condiviso. A tale scopo, aggiungere una voce nella sezione Elemento webParts (schema delle impostazioni ASP.NET) del file Web.config.
