Hinweise
Bei Verwendung des Webparts-Steuerelementsatzes können Sie zwei Serversteuerelemente aktivieren, um eine Verbindung herzustellen und Daten freizugeben. Dabei übernimmt ein Steuerelement die Funktion des Datenanbieters und das andere die Funktion des Datenconsumers. Die zwei Steuerelemente können WebPart-Steuerelemente oder einen anderen beliebigen Serversteuerelement-Typ darstellen, vorausgesetzt, sie wurden zum Behandeln von Verbindungen entwickelt und befinden sich in einer WebPartZoneBase-Zone.
Weitere Informationen zum ConnectionsZone-Steuerelement und zu Webparts-Steuerelementen finden Sie unter ASP.NET Web Parts Pages.
Beispiel
Im folgenden Codebeispiel wird veranschaulicht, wie das ConnectionsZone-Steuerelement auf einer Webseite deklarativ verwendet wird. Innerhalb des Elements wird eine Anzahl von Eigenschaften deklarativ festgelegt. Andere Eigenschaften der Verbindungszone werden programmgesteuert im script-Abschnitt der Seite festgelegt.
Die Definitionen für das Benutzersteuerelement und das mit @ Register-Direktiven definierte benutzerdefinierte Steuerelement finden Sie unter "Example" in der Klassenübersicht für ConnectionsZone.
