Exemples

L'exemple de code suivant montre une méthode substituée WebPart.PartCommunicationInit qui crée une instance de la classe ListProviderInitEventArgs à envoyer lors de l'événement ListProviderInit se produit. Cet exemple de code fait partie d'un exemple plus développé fourni pour l'interface IListProvider .

 ' 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)

   End If
End Sub 'PartCommunicationInit
