Beispiele

Im folgenden Codebeispiel wird die Verwendung der HelpVerb -Eigenschaft für ein WebPartZone Steuerelement veranschaulicht.

Damit das Codebeispiel funktioniert, benötigen Sie zusätzlich zum folgenden Code ein benutzerdefiniertes WebPart Steuerelement. Sie können entweder Ihr eigenes Steuerelement oder den Code für das benutzerdefinierte TextDisplayWebPart Steuerelement verwenden, das Sie im Abschnitt Beispiel der WebPart Klassenübersicht finden.

Dieses Codebeispiel enthält ein Benutzersteuerelement, mit dem Sie die Anzeigemodi auf einer Webseite ändern können. Weitere Informationen zu Anzeigemodi und dem Quellcode in diesem Steuerelement finden Sie unter Exemplarische Vorgehensweise: Ändern von Anzeigemodi auf einer Webpartseite.

Dieses Codebeispiel enthält auch eine HTML-Seite, die Hilfeinhalte für das TextDisplayWebPart Steuerelement enthalten kann. Damit dieses Beispiel funktioniert, müssen Sie den folgenden Code in einer Datei namens Textwebparthelp.htm speichern und ihn im gleichen Verzeichnis Ihrer Website wie die .aspx Seite platzieren, die das TextDisplayWebPart Steuerelement hostet.

<html>  
<head runat="server">  
    <title>Text Content WebPart Help</title>

Beachten Sie auch, dass die HelpVerb -Eigenschaft deklarativ für das <asp:WebPartZone> -Element verwendet wird, um den Text für das Verb festzulegen, wie im folgenden Codebeispiel gezeigt.

<asp:WebPartZone ID="WebPartZone1" Runat="server">
  <CloseVerb Text="Close WebPart" />
  <HelpVerb Text="View Help" />
  <ExportVerb Text="Export WebPart Definition" />
  <DeleteVerb Text ="Delete WebPart" />
  <MinimizeVerb Description="Minimize the control" />
  <RestoreVerb Description="Restore the control" />
  <ZoneTemplate>
  </ZoneTemplate>  
</asp:WebPartZone>

<asp:WebPartZone ID="WebPartZone1" Runat="server">
  <CloseVerb Text="Close WebPart" />
  <HelpVerb Text="View Help" />
  <ExportVerb Text="Export WebPart Definition" />
  <DeleteVerb Text ="Delete WebPart" />
  <MinimizeVerb Description="Minimize the control" />
  <RestoreVerb Description="Restore the control" />
  <ZoneTemplate>
  </ZoneTemplate>  
</asp:WebPartZone>

Beachten Sie abschließend im folgenden Codebeispiel, dass die HelpUrl -Eigenschaft für das <aspSample:TextDisplayPart> -Element festgelegt ist, um die URL für die Hilfedatei bereitzustellen.

<asp:CatalogZone ID="CatalogZone1" Runat="server">
  <ZoneTemplate>
    <asp:DeclarativeCatalogPart ID="DeclarativeCatalogPart1" 
      Runat="server">

          id="textwebpart" 
          title = "Text Content WebPart" 
          width="350px" 
          AllowClose="true"

Nachdem Sie die Seite in einem Browser geladen haben, klicken Sie im Dropdownlistensteuerelement Anzeigemodus auf das Menüelement Katalogmodus , um die Seite in den Kataloganzeigemodus zu wechseln. Fügen Sie das TextDisplayWebPart Steuerelement zur Seite hinzu, schließen Sie den Katalog, und kehren Sie die Seite in den normalen Browsermodus zurück. Wenn Sie auf das Dropdownmenü Verben in der Titelleiste des TextDisplayWebPart Steuerelements klicken, können Sie auf das Hilfeverb zugreifen, um die Seite Hilfe zu öffnen.

Hinweise

Auf die HelpVerb Eigenschaft kann entweder deklarativ oder programmgesteuert zugegriffen werden. Sie können deklarativ innerhalb einer Zone darauf zugreifen, indem Sie das <asp:HelpVerb> -Element verwenden, um den Text, die Beschreibung, die Aktivierung des Verbs und andere Attribute festzulegen. Es ist jedoch nicht erforderlich, ein Hilfeverb für eine Zone zu deklarieren, da es standardmäßig aktiviert ist. Der einzige Schritt, der erforderlich ist, damit ein Hilfeverb zur Laufzeit im Verbenmenü von WebPart Steuerelementen in einer Zone angezeigt werden kann, besteht darin, der HelpUrl Eigenschaft für einzelne WebPart Steuerelemente einen Wert zuzuweisen.
