Beispiele
Das folgende Codebeispiel zeigt eine überschriebene WebPart.PartCommunicationMain-Methode, die erstellt eine Instanz der Klasse ListReadyEventArgs zu senden, wenn das ListReady -Ereignis tritt auf. Dieses Codebeispiel ist Teil eines umfangreicheren Beispiels für die IListProvider -Schnittstelle.
' Step #8: 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 ListReady or PartialListReady
' event. Some parts may not behave properly if they are left waiting
' for this information.
Public Overrides Sub PartCommunicationMain()
' Ensure that all of the Web Part's controls are created.
' Ensure that all of the Web Part's controls are created.
EnsureChildControls()
' Check if connected
If _connected Then
' If there is a listener, fire the ListReady event.
If Not (ListReady Is Nothing) Then
' Create the ListReadyEventArgs object for the ListProviderInit event.
Dim listReadyArgs As New ListReadyEventArgs()
' If user clicked button, send the value.
If _listButtonClicked Then
' Set the List to the value of the table in the DataGrid.
' This is the value that will be sent to the consumer Web
' Part.
listReadyArgs.List = CType(_dataGrid.DataSource, DataTable)
Else
' The user didn't click the button, so send a
' null DataTable to the consumer Web Part.
listReadyArgs.List = Nothing
End If
' Fire the ListReady event.
' The consumer Web Part will receive the DataTable.
ListReady(Me, listReadyArgs)
