Examples
O exemplo de código a seguir mostra um método substituído WebPart.PartCommunicationInit que cria uma instância da classe ListProviderInitEventArgs para enviar quando ocorre o evento ListProviderInit . Este exemplo de código é parte de um exemplo maior fornecido para a interface IListProvider .
' Step #7: Override 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. Some parts
' may not behave properly if this initialization information is not received.
Public Overrides Sub PartCommunicationInit()
' 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
'Create the ListProviderInitEventArgs object for the ListProviderInit event.
Dim listProviderInitArgs As New ListProviderInitEventArgs()
' Set the list field names.
listProviderInitArgs.FieldList = _listFieldNames
listProviderInitArgs.FieldDisplayList = _listFieldDisplayNames
' Fire the ListProviderInit event.
ListProviderInit(Me, listProviderInitArgs)
End If
