Feldwert

Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie Sie mithilfe eines MultiView -Steuerelements eine einfache Umfrage erstellen. Jedes View Steuerelement ist eine separate Umfragefrage. Die PreviousViewCommandName Felder und NextViewCommandName werden verwendet, um eine automatische Navigation zwischen dem vorherigen und dem nächsten View Steuerelement in der Umfrage bereitzustellen.

Hinweis

Im folgenden Codebeispiel wird das Einzeldateicodemodell verwendet. Es funktioniert möglicherweise nicht ordnungsgemäß, wenn es direkt in eine CodeBehind-Datei kopiert wird. Dieses Codebeispiel muss in eine leere Textdatei mit einer .aspx-Erweiterung kopiert werden. Weitere Informationen zum Web Forms-Codemodell finden Sie unter ASP.NET Web Forms-Seitencodemodell.

Hinweise

Verwenden Sie das PreviousViewCommandName Feld, um den Befehlsnamen "PrevView" darzustellen.

Sie können den Wert dieses Felds verwenden, um die Vorteile der MultiView automatischen Aktualisierung des aktiven View Steuerelements zu nutzen. Wenn ein View Steuerelement beispielsweise ein Button Steuerelement enthält, das zum nächsten Viewnavigiert, können Sie die CommandName Eigenschaft auf den Wert des Felds festlegen, der PreviousViewCommandName "PrevView" ist. Dadurch erhöht das MultiView Steuerelement automatisch den Wert der ActiveViewIndex Eigenschaft, wenn auf die Schaltfläche geklickt wird.
