WebPartConnection.ConsumerID 屬性

定義

取得或設定連接上的屬性值,這個屬性會參考做為此連接之消費者 WebPart 控制項的 ID。

public:
 property System::String ^ ConsumerID { System::String ^ get(); void set(System::String ^ value); };
public string ConsumerID { get; set; }
member this.ConsumerID : string with get, set
Public Property ConsumerID As String

屬性值

字串,包含做為連接之中消費者控制項的 ID。

範例

下列程式代碼範例示範 屬性的 ConsumerID 宣告式和程序設計用法。

此範例有四個部分:

  • 使用者控制元件,可讓您變更頁面上的網頁元件顯示模式。

  • 介面的原始程式碼,以及 WebPart 兩個做為連接提供者和取用者的控件。

  • 裝載所有控制項並執行程式碼範例的網頁。

  • 如何執行範例頁面的說明。

此程式代碼範例的第一個部分是使用者控制項,可讓使用者變更網頁上的顯示模式。 將下列原始程式碼儲存至 .ascx 檔案,為其提供指派給 Src 這個使用者控件之 指示詞之 屬性的 Register 檔名,其位於主控網頁頂端附近。 如需此控件中顯示模式和原始碼描述的詳細資訊,請參閱逐步解說 :變更網頁元件頁面上的顯示模式

程式代碼範例的第三個部分是網頁。 請注意,使用 <StaticConnections><asp:WebPartsConnection> 元素在頁面標記中宣告連接。 連接宣告包含必要 ConsumerID 屬性。 建立連接的第二個方法會出現在方法中 Button1_Click ,其中程式代碼會使用取用者控件中定義的連接點來建立新的連接。 然後,在方法中 Button2_Click ,程式代碼會存取 屬性的值, ConsumerID 並將其顯示在標籤中。
