CellProviderInitEventArgs class
NOTE: This API is now obsolete.
Mantém a estrutura de dados é inicializada quando um ICellProvider Web Part cria uma conexão e dispara um evento CellConsumerInit para uma interface ICellConsumer . Não pode ser herdada.

Examples
O exemplo de código a seguir mostra um método substituído PartCommunicationInit que cria uma estrutura de dados para conter os valores das propriedades FieldName e FieldDisplayNameCellProviderInitEventArgs , define os valores de propriedade e dispara o evento CellProviderInit . Este exemplo de código é parte de um exemplo maior fornecido para a interface ICellProvider .
' Step #9: 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 InitEventArgs structure for the CellProviderInit event.
Dim cellProviderInitArgs As New CellProviderInitEventArgs()
' Set the FieldName and FieldDisplay values.
cellProviderInitArgs.FieldName = _cellName
cellProviderInitArgs.FieldDisplayName = _cellDisplayName
' Fire the CellProviderInit event.
RaiseEvent CellProviderInit(Me, cellProviderInitArgs)
End If
