Exemples

L'exemple de code suivant montre une méthode desubstitué WebPart.PartCommunicationInitqui crée une structure de données CellProviderInitEventArgs pour contenir les valeurs des propriétés FieldName et FieldDisplayName , définit les valeurs de propriété, puis déclenche l'événement CellProviderInit . Cet exemple de code fait partie d'un exemple plus développé fourni pour l'interface ICellProvider .

      ' Step #9: Override the 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 as 
      ' some parts
      ' may not behave properly if this initialization information is 
      ' not received.
      Public Overrides Sub PartCommunicationInit()
        ' Check if connected
         If _connected Then                                
           ' Create the InitEventArgs structure for the 
           ' CellProviderInit event.
            Dim cellProviderInitArgs As New CellProviderInitEventArgs()

            ' Set the FieldName and FieldDisplay values.
             cellProviderInitArgs.FieldName = _cellName
             cellProviderInitArgs.FieldDisplayName = _cellDisplayName

            ' Fire the CellProviderInit event. 
            RaiseEvent CellProviderInit(Me, cellProviderInitArgs)

          End If
      End Sub

        // Step #9: Override the PartCommunicationInit() method

        // It is important to always pass initialization information as

        public override void PartCommunicationInit()
        {
            // Check if connected
            if(_connected)
            {
                // If there is a listener, fire the CellProviderInit 
                // event.
                if (CellProviderInit != null)
                {
                    // Create the InitEventArgs structure for the 
                    // CellProviderInit event.
                    CellProviderInitEventArgs cellProviderInitArgs = 
                       new CellProviderInitEventArgs();
                    
                    // Set the FieldName and FieldDisplay values.
                    cellProviderInitArgs.FieldName = _cellName;
                    cellProviderInitArgs.FieldDisplayName = 
                       _cellDisplayName;
                    
                    // Fire the CellProviderInit event.
                    CellProviderInit(this, cellProviderInitArgs);
