Deklarative Syntax des ProxyWebPartManager-Webserver-Steuerelements

Aktualisiert: November 2007

Bietet Entwicklern die Möglichkeit, statische Verbindungen auf einer Inhaltsseite zu deklarieren, wenn ein WebPartManager-Steuerelement auf der der Inhaltsseite zugeordneten Masterseite deklariert wurde.

Hinweise

Mit dem ProxyWebPartManager-Steuerelement können statische Verbindungen auf Inhaltsseiten deklariert werden, wenn ein WebPartManager-Steuerelement bereits auf einer Masterseite deklariert wurde.

Weitere Informationen zum ProxyWebPartManager-Steuerelement und zum Webparts-Steuerelement finden Sie unter ASP.NET-Webparts-Steuerelemente.

Beispiel

Im folgenden Codebeispiel wird veranschaulicht, wie mithilfe der ProxyWebPartManager-Klasse statische Verbindungen auf Inhaltsseiten in einer Anwendung deklariert werden, in der Masterseiten verwendet werden.

Definitionen des Benutzersteuerelements und des mit @ Register-Direktiven definierten benutzerdefinierten Steuerelements und der Masterseite, auf die mit dem MasterPageFile-Attribut in der @ Page-Direktive verwiesen wird, finden Sie unter "Example" in der Klassenübersicht für ProxyWebPartManager.
