请注意：此 API 现在已过时。
提供FieldName和FieldDisplayName到实现ICellConsumer接口的 Web 部件的属性值。
命名空间： Microsoft.SharePoint.WebPartPages.Communication
程序集： Microsoft.SharePoint（位于 Microsoft.SharePoint.dll 中）
语法
声明
<ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartField instead")> _
Event CellProviderInit As CellProviderInitEventHandler
用法
Dim instance As ICellProvider
Dim handler As CellProviderInitEventHandler
AddHandler instance.CellProviderInit, handler
[ObsoleteAttribute("Use System.Web.UI.WebControls.WebParts.IWebPartField instead")]
event CellProviderInitEventHandler CellProviderInit
示例
下面的代码示例演示重写的WebPart.PartCommunicationInit方法创建一个CellProviderInitEventArgs数据结构包含FieldName和FieldDisplayName属性值，设置属性值，然后将触发CellProviderInit事件。此代码示例是示例的一个更大提供的ICellProvider接口的一部分。
' 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
End Sub
