HINWEIS: Diese API ist veraltet.
Enthält die Feldnamen und ein optionales Feld Anzeigenamen für die Liste zur Verfügung gestellt von einem Webpart, das die IListProviderinterface implementiert wird, wenn das ListProviderInit -Ereignis eintritt.

Beispiele
Das folgende Codebeispiel zeigt eine überschriebene WebPart.PartCommunicationInit -Methode, die erstellt eine Instanz der Klasse ListProviderInitEventArgs zu senden, wenn das ListProviderInit -Ereignis tritt auf. Dieses Codebeispiel ist Teil eines umfangreicheren Beispiels für die IListProvider -Schnittstelle.
' Step #7: Override PartCommunicationInit method.
' PartCommunicationInit() 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 Overrides Sub PartCommunicationInit()
' Ensure that all of the Web Part's controls are created.
' Ensure that all of the Web Part's controls are created.
EnsureChildControls()
' Check if connected.
If _connected Then
'Create the ListProviderInitEventArgs object for the ListProviderInit event.
Dim listProviderInitArgs As New ListProviderInitEventArgs()
' Set the list field names.
listProviderInitArgs.FieldList = _listFieldNames
listProviderInitArgs.FieldDisplayList = _listFieldDisplayNames
' Fire the ListProviderInit event.
ListProviderInit(Me, listProviderInitArgs)

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