範例

下列程式碼範例示範搭配控制項使用 CancelVerb 屬性 ConnectionsZone 。此範例只包含示範屬性使用之網頁的程式碼;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 ConnectionsZone 觀取得此程式碼。
原始程式檔，其中包含郵遞區號介面的程式碼，以及兩 WebPart 個做為提供者和取用者連線的控制項。從類別概 ConnectionsZone 觀取得此程式碼。
裝載所有控制項、宣告 <asp:connectionszone> 專案，以及示範如何以宣告方式和程式設計方式使用屬性的網頁。
說明範例在瀏覽器中的運作方式。

網頁會宣告專案 <asp:connectionszone> ，並在元素內宣告 <cancelverb> 元素，並使用屬性設定某些屬性。此外，在方法中 Page_PreRender ，程式碼會在控制項的 cancel 動詞 ConnectionsZone 命令上設定一些屬性。

在瀏覽器中載入頁面。使用 顯示模式 控制項切換至連接模式。按一下 郵遞區號提供者 控制項上的動詞功能表箭號，然後按一下連接動詞命令。按一下 [ 結束連接 ] 按鈕，以中斷由於頁面上宣告式連線而已連接的控制項。按一下 [ 選取提供者的取用者] 以與超連結連線 ，並注意設定各種屬性的效果。如果您將滑鼠指標放在 [終止 ] 按鈕上方，自訂描述文字會出現在工具提示中。

備註

取消動詞與控制項搭配使用 ConnectionsZone ，是區域層級動詞，會出現在連接使用者介面 (UI) 作為使用者選取控制項連接點的檢視的一部分。當使用者按一下取消動詞時，它會取消選取連接點的程式，並將連線區域檢視傳回給使用者可以按一下以建立新連線的超連結。

CancelVerb使用屬性取得 UI 中對應 WebPartVerb 物件的參考。雖然屬性本身是唯讀的，但在您有動詞的參考之後，您可以視需要變更其屬性值。

您可以宣告專案標記內的專案，以 <cancelverb> 宣告方式設定取消動詞的 <asp:connectionszone> 屬性值。動詞的屬性可以宣告方式在表單 Property-Subproperty 中設定，其中 Subproperty 是物件的屬性 WebPartVerb (，例如， CancelVerb-Text) 。您也可以以程式設計方式在表單 Property.Subproperty 中設定屬性，例如 () CancelVerb.Text 。
