Exemples

L'exemple de code suivant montre une méthode substituée WebPart.PartCommunicationInit qui crée un objet RowProviderInitEventArgs , définit les noms de champs et affiche les noms puis déclenche l'événement RowProviderInit . Cet exemple de code fait partie d'un exemple plus développé fourni pour l'interface Microsoft.SharePoint.WebPartPages.Communication.IRowProvider .

      ' Step #7: Override the PartCommunicationInit() method.
      ' The PartCommunicationInit method 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 RowProviderInitEventArgs object for the RowProviderInit event.
                Dim rowProviderInitEventArgs As New RowProviderInitEventArgs()

                ' Set the row field names.
                rowProviderInitEventArgs.FieldList = _rowFieldNames

                ' Set the row field display names.
                rowProviderInitEventArgs.FieldDisplayList = _rowFieldDisplayNames

                ' Fire the RowProviderInit event.
                RaiseEvent RowProviderInit(Me, rowProviderInitEventArgs)
            End If
        End Sub

        // It is important to always pass initialization information. Some parts

        public override void PartCommunicationInit()
        {

            EnsureChildControls();

            // Check if connected.
            if(_connected)
            {
                // If there is a listener, fire the RowProviderInit event.
                if (RowProviderInit != null)

                    RowProviderInit(this, rowProviderInitEventArgs);
