Style.Font Eigenschaft
Definition
Wichtig
Einige Informationen beziehen sich auf Vorabversionen, die vor dem Release ggf. grundlegend überarbeitet werden. Microsoft übernimmt hinsichtlich der hier bereitgestellten Informationen keine Gewährleistungen, seien sie ausdrücklich oder konkludent.
Ruft die Schriftarteigenschaften ab, die dem Webserversteuerelement zugeordnet sind.
public:
property System::Web::UI::WebControls::FontInfo ^ Font { System::Web::UI::WebControls::FontInfo ^ get(); };public System.Web.UI.WebControls.FontInfo Font { get; }member this.Font : System.Web.UI.WebControls.FontInfoPublic ReadOnly Property Font As FontInfoEigenschaftswert
Eine FontInfo, die die Schriftarteigenschaften des Webserver-Steuerelements darstellt.
Beispiele
In diesem Beispiel wird veranschaulicht, wie Sie mithilfe eines Style Objekts die Formatvorlageneigenschaften mehrerer Steuerelemente gleichzeitig ändern können. Jedes Mal, wenn eines der Style Eigenschaftswerte geändert wird, muss jedes Steuerelement seine ApplyStyle Methode aufrufen. Beachten Sie, dass nicht alle enthaltenen Steuerelemente alle gezeigten Eigenschaften unterstützen. Wenn ein Steuerelement keine bestimmte Eigenschaft unterstützt, ändert sich das Erscheinungsbild des Steuerelements nicht, wenn der Eigenschaftswert geändert wird.
Hinweis
Im folgenden Codebeispiel wird das Einzeldateicodemodell verwendet und funktioniert möglicherweise nicht ordnungsgemäß, wenn sie direkt in eine CodeBehind-Datei kopiert werden. Dieses Codebeispiel muss in eine leere Textdatei kopiert werden, die über eine ASPX-Erweiterung verfügt. Weitere Informationen zum Web Forms Codemodell finden Sie unter ASP.NET Web Forms Seitencodemodell.

Hinweise
Verwenden Sie die Font Eigenschaft, um die Schriftarteigenschaften des Webserversteuerelements anzugeben. Diese Eigenschaft enthält Untereigenschaften, auf die deklarativ in Form von Property-Subproperty (z. B. ) oder programmgesteuert in Form von Property.Subproperty (z. B. ) zugegriffen werden kann (zFont.Bold. BFont-Bold. ).
Alle untergeordneten Eigenschaften werden in Browsern vor Microsoft Internet Explorer Version 4 für alle Steuerelemente gerendert. Sie sind: Bold, , NameUnderlineStrikeoutNamesSize Italicund (aber nur benannte Schriftgrößen wie , Small``Smallerusw.) funktionieren.
Hinweis
Obwohl diese Untereigenschaften in Browsern vor Microsoft Internet Explorer Version 4 gerendert werden, unterscheidet sich der gerenderte HTML-Code anders als in späteren Browsern. Anstatt als Formatattribute zu rendern, werden diese Untereigenschaften als HTML-Elemente wie z <b> . B. und <font>.
Eine Untereigenschaft, die nicht in einigen Browsern gerendert wird, ist Overline.
