Exemples

L'exemple de code suivant montre une méthode substituée WebPart.PartCommunicationMain qui crée un objet RowReadyEventArgs , définit les valeurs de ligne et l'état de sélection, puis déclenche l'événement RowReady . Cet exemple de code fait partie d'un exemple plus développé fourni pour l'interface IRowProvider .

' Step #8: Override the PartCommunicationMain method.
' The PartCommunicationMain method is called by the Web Part 
' infrastructure on the client during the 
' ASP.NET PreRender event to allow the part to pass its primary data to 
' the other connected parts.
' It is important to always fire the RowReady event. Some parts
' may not behave properly if they are left waiting for this 
' information.
Public Overrides Sub PartCommunicationMain()
   ' Check if connected
   If _connected Then
      'If there is a listener, fire the RowReady event.
      If Not (RowReady Is Nothing) Then
         ' Create the RowReadyEventArgs object for the RowReady event.
         Dim rowReadyEventArgs As New RowReadyEventArgs()
               
         ' Declare data Variables.
         Dim selectionStatus As String = ""
         Dim dr(0) As DataRow
