Esempio
Nell'esempio di codice seguente viene illustrato come usare la HeaderCloseVerb proprietà con un controllo ereditato ToolZone . Nell'esempio viene illustrato come abilitare e disabilitare il verbo di chiusura nell'intestazione di un EditorZone controllo.
La prima parte dell'esempio di codice è un controllo utente a cui viene fatto riferimento nella pagina e consente di passare la pagina a modalità di visualizzazione diverse. Per altre informazioni sulle modalità di visualizzazione e su come consentire agli utenti di spostarsi tra di essi, vedere Procedura dettagliata: Modifica delle modalità di visualizzazione in una pagina web part.

La seconda parte dell'esempio di codice è la pagina Web. La pagina contiene un EditorZone controllo che eredita dalla ToolZone classe . Il Button1_Click metodo nella pagina imposta il valore della HeaderCloseVerb proprietà.
Si noti che dopo il caricamento della pagina, è necessario attivare la modalità di modifica della pagina per visualizzare gli effetti del codice che usa la HeaderCloseVerb proprietà nel EditorZone controllo . Quando si fa clic sul pulsante Abilita/Disabilita chiudi verbo , il verbo nell'intestazione della zona deve essere abilitato e disabilitato in alternativa.
