Esempio

Nell'esempio di codice seguente viene illustrato come usare la HeaderVerbStyle proprietà con un controllo ereditato ToolZone . Nell'esempio viene illustrato come modificare la larghezza del bordo intorno a un EditorZone controllo usando questa proprietà.

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 diverse modalità di visualizzazione. Per altre informazioni sulle modalità di visualizzazione e consentire agli utenti di passare tra di loro, 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 HeaderVerbStyle proprietà.

Si noti che dopo il caricamento della pagina, è necessario passare la pagina in modalità di modifica per visualizzare gli effetti del codice che usa la HeaderCloseVerb proprietà nel EditorZone controllo. Quando si fa clic sul pulsante Toggle Header Verb Border ,la larghezza del bordo intorno alla zona deve cambiare.
