IListProvider.ListProviderInit-Ereignis
HINWEIS: Diese API ist veraltet.
Tritt auf, wie die Initialisierungsereignis, das eine Liste von Feldnamen der Daten und einer optionalen Liste mit Anzeigenamen von Feldern mit einem Webpart bereitstellt, die die IListConsumer -Schnittstelle implementiert wird.

Beispiele
Im folgenden Codebeispiel wird überschreibt die PartCommunicationInit -Methode und löst das ListProviderInit -Ereignis. 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.
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.
RaiseEvent ListProviderInit(Me, listProviderInitArgs)
End If
