參考

定義

命名空間:: System.Web.UI.WebControls.WebParts

組件:: System.Web.dll

重要

部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。

當 Web 組件控制項沒有現有連接時，取得或設定在連接使用者介面 (UI) 主體中出現的指示文字。

public:
 virtual property System::String ^ NoExistingConnectionInstructionText { System::String ^ get(); void set(System::String ^ value); };

public virtual string NoExistingConnectionInstructionText { get; set; }

member this.NoExistingConnectionInstructionText : string with get, set

Public Overridable Property NoExistingConnectionInstructionText As String

屬性值

String

在沒有現有連接的狀況下，包含文字訊息的字串。 .NET Framework 會提供文化特性字串做為預設文字。

範例

下列程式碼範例示範搭配控制項使用 NoExistingConnectionInstructionText 屬性 ConnectionsZone 。此範例只包含示範使用屬性之網頁的程式碼;如需執行範例所需的其他兩個程式碼檔案，請參閱類別概觀的 ConnectionsZone 範例一節。程式碼範例有四個部分：

使用者控制項，可讓您在網頁上切換顯示模式。從類別概觀取得 ConnectionsZone 此程式碼。
包含郵遞區號介面程式碼的來源檔案，以及兩 WebPart 個控制項做為連線的提供者和取用者。從類別概觀取得 ConnectionsZone 此程式碼。
裝載所有控制項的網頁、宣告 <asp:connectionszone> 專案，並示範如何以程式設計方式使用屬性。
說明範例如何在瀏覽器中運作。

網頁會 <asp:connectionszone> 宣告專案，並在方法中 Page_PreRender ，程式碼會將值指派給 NoExistingConnectionInstructionText 屬性。

在瀏覽器中載入頁面。使用 顯示模式 控制項切換至連線模式。按一下 [郵遞區號取用者 ] 控制項上的動詞功能表箭號，然後按一下 [連接動詞]。在針對現有連線開啟的檢視中，按一下 [結束連線 ] 按鈕。請注意，沒有現有連線的指令文字會出現在連接 UI 底部附近，緊接在區域頁尾區域的關閉動詞上方。

備註

每當顯示連接 UI 且沒有任何連接存在時，就會顯示內容中包含的 NoExistingConnectionInstructionText 文字。當使用者將頁面切換成連接顯示模式，然後按一下控制項動詞功能表上的 WebPart 連接動詞，就會顯示主要連接 UI。如果沒有目前的連接，屬性中的 NoExistingConnectionInstructionText 文字會顯示在連接 UI 底部附近，就在區域頁尾區域的關閉動詞上方。文字描述沒有現有連線的事實，並提供使用者在 UI 內建立連線的基本指示。

您可以藉由新增名為 NoExistingConnectionInstructionText 的屬性，並為其指派值，以宣告方式在元素的 <asp:connectionszone> 開頭標記內設定這個屬性的值。您也可以以程式設計方式設定屬性值。
