Ejemplos

En el ejemplo de código siguiente se muestra un método deinvalidado WebPart.PartCommunicationMainque crea una estructura de datos de CellReadyEventArgs para que contenga el valor de la propiedad Cell , se establece el valor de propiedad y, a continuación, se desencadena el evento CellReady . Este ejemplo de código forma parte de un ejemplo más extenso de la interfaz 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
