Ejemplos

En el ejemplo de código siguiente se reemplaza el método PartCommunicationInit y se desencadena el evento ListProviderInit . Este ejemplo de código forma parte de un ejemplo más extenso de la interfaz 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.
            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
        End Sub

public override void PartCommunicationInit()

            // Fire the ListProviderInit event.
            ListProviderInit(this, listProviderInitArgs);
