Exemples
L'exemple de code suivant montre une méthode substituée PartCommunicationMain qui crée une structure de données CellReadyEventArgs pour contenir la valeur de la propriété Cell , définit la valeur de la propriété, puis déclenche l'événement CellReady . Cet exemple de code fait partie d'un exemple plus développé fourni pour l'interface ICellProvider .
' 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.
If _cellClicked Then
' Set the cell to the value of the TextBox text.
' This is the value that will be sent to the Consumer
cellReadyArgs.Cell = _cellInput.Text
Else
' The user didn't actually click the button
' so just send an empty string to the consumer.
cellReadyArgs.Cell = ""
End If
' Fire the CellReady event.
' The Consumer will receive the cell value in its
' CellReady event handler
RaiseEvent CellReady(Me, cellReadyArgs)
End If
End If
