下列程式碼範例示範覆寫的PartCommunicationMain方法，建立CellReadyEventArgs資料結構，包含Cell屬性值、 設定屬性值，並再引發CellReady事件。這個程式碼範例是提供ICellProvider介面的完整範例的一部分。
' Step #10: 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 CellReady 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 CellReady event.
If Not (CellReady Is Nothing) Then
' Create the CellReadyEventArgs data structure for the
' CellProviderInit event.
Dim cellReadyArgs As New CellReadyEventArgs()
' If the user clicked the button, then send the value.
