Beispiele

Das folgende Codebeispiel zeigt eine überschriebene PartCommunicationInit -Methode, die erstellt eine Instanz der Klasse ParametersInConsumerInitEventArgs und Parameterwerte durch Erstellen einer Instanz der ParameterInProperty -Klasse definiert. Dieses Codebeispiel ist Teil eines umfangreicheren Beispiels für die IParametersInConsumer -Schnittstelle.

// Step #7: Override the PartCommunicationInit method.
// The PartCommunicationInit method is called by the Web Part infrastructure during the ASP.NET PreRender 
// event to allow the part to pass initialization information to the other connected parts.
// It is important to always pass initialization information. Some parts
// may not behave properly if this initialization information is not received.
public override void PartCommunicationInit()

    // Ensure all controls have been created.
    EnsureChildControls();
