Ejemplos

En el ejemplo de código siguiente se muestra un método invalidado PartCommunicationInit que crea el objeto CellConsumerInitEventArgs , se establece sus propiedades FieldName y FieldDisplayName y, a continuación, se desencadena el evento CellConsumerInit . Este ejemplo de código forma parte de un ejemplo más extenso de la interfaz ICellConsumer .

' Step #10: Override the 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 as some 
' parts may not behave properly if this initialization information 
' is not received.
Public Overrides Sub PartCommunicationInit()
    ' Check if connected.
    If _connected Then
        ' Create the CellConsumerInitEventArgs structure for the 
        ' CellConsumerInit event.
        Dim cellConsumerInitArgs As New CellConsumerInitEventArgs()

        ' Set the FieldName and FieldDisplayName values.
        cellConsumerInitArgs.FieldName = _cellName
        cellConsumerInitArgs.FieldDisplayName = _cellDisplayName

        ' Fire the CellConsumerInit event.
        RaiseEvent CellConsumerInit(Me, cellConsumerInitArgs)
    End If
End Sub
