Beispiele
Das folgende Codebeispiel zeigt eine überschriebene GetInitEventArgs -Methode, die eine Instanz der Klasse InitEventArgs zurückgibt. Dieses Codebeispiel ist Teil eines umfangreicheren Beispiels für die IFilterConsumer -Schnittstelle.
' Step #8: Override the GetInitEventArgs method.
' GetInitEventArgs() is called by the Web Part infrastructure during
' the ASP.NET PreRender event to gather the
' necessary information it needs to build the transformer dialog. The
' transformer dialog is needed when connecting different interfaces
' such as IRowProvider to ICellConsumer. The transformer dialog allows
' the user to map the fields between the interfaces. The
' GetInitEventArgs()method only needs to be implemented for interfaces
' that can participate in a transformer which are the following:
' ICellConsumer, IRowProvider, IFilterConsumer, IParametersOutProvider,
' IParametersInConsumer.
' <param name="interfacename">Name of interface on which the Web Part
' infrastructure is requesting information</param>
' <returns>An InitEventArgs object</returns>
Public Overrides Function GetInitEventArgs(interfaceName As String) As InitEventArgs
' Check if this is my particular cell interface.
If interfaceName = "MyFilterConsumerInterface" Then
'Ensure that all of the Web Part's controls are created.
'The _filterFieldNames and _filterFieldDisplayNames are set during EnsureChildControls()
EnsureChildControls()
' Create the FilterConsumerInitEventArgs object for the FilterConsumerInit event.
Dim filterConsumerInitArgs As New FilterConsumerInitEventArgs()
' Set the field names
filterConsumerInitArgs.FieldList = _filterFieldNames
filterConsumerInitArgs.FieldDisplayList = _filterFieldDisplayNames
' return the FilterConsumerInitEventArgs.
Return filterConsumerInitArgs

Threadsicherheit
Alle öffentlichen static (Shared in Visual Basic) Member dieses Typs sind threadsicher. Die Threadsicherheit von Instanzmembern ist nicht gewährleistet.
