CellProviderInitEventArgs class

NOTE: This API is now obsolete.

保存時ICellProvider網頁組件中建立的連接，並會引發CellConsumerInit事件ICellConsumer介面初始化的資料結構。無法被繼承。

下列程式碼範例示範覆寫的PartCommunicationInit方法，建立CellProviderInitEventArgs資料結構，包含FieldName和FieldDisplayName屬性值、 設定屬性值，並再引發CellProviderInit事件。這個程式碼範例是提供ICellProvider介面的完整範例的一部分。
