属性: PersistenceModeAttribute

示例

下面的代码示例演示如何将 CancelVerb 属性与控件一起使用 ConnectionsZone 。该示例仅包含演示如何使用该属性的网页的代码;有关运行示例所需的其他两个代码文件，请参阅类概述的 ConnectionsZone “示例”部分。代码示例有四个部分：

允许用户在网页上切换显示模式的用户控件。从 ConnectionsZone 类概述中获取此代码。
包含邮政编码接口的代码的源文件，以及充当连接提供程序和使用者的两 WebPart 个控件。从 ConnectionsZone 类概述中获取此代码。
承载所有控件的网页，声明元素 <asp:connectionszone> ，并演示如何以声明方式和编程方式使用属性。
说明示例在浏览器中的工作原理。

网页声明元素 <asp:connectionszone> ，并在元素中声明 <cancelverb> 元素，并使用属性设置一些属性。此外，在 Page_PreRender 方法中，代码为控件的 cancel 谓词 ConnectionsZone 设置一些属性。

在浏览器中加载页面。使用 显示模式 控件切换到连接模式。单击 邮政编码提供程序 控件上的谓词菜单箭头，然后单击连接谓词。单击“ 结束连接 ”按钮可断开由于页面上声明性连接而已连接的控件的连接。单击 提供程序的“选择使用者”以使用超链接进行连接 ，并注意设置各种属性的效果。如果将鼠标指针放在 “终止 ”按钮上，自定义说明文本会显示在工具提示中。

注解

取消谓词与控件一起使用 ConnectionsZone ，是一个区域级谓词，显示在连接用户界面 (UI) 作为用户为控件选择连接点的视图的一部分。当用户单击取消谓词时，它会取消选择连接点的过程，并将连接区域视图返回到用户可以单击以建立新连接的超链接。

使用属性 CancelVerb 获取对 UI 中相应 WebPartVerb 对象的引用。尽管属性本身是只读的，但在对谓词有引用后，可以根据需要更改其属性值。

可以通过在元素的标记中声明 <cancelverb> 元素，以声明方式设置取消谓词的 <asp:connectionszone> 属性值。可以在窗体 Property-Subproperty中以声明方式设置谓词的属性，其中 Subproperty 对象的属性 WebPartVerb (例如 CancelVerb-Text) 。还可以以编程方式在窗体 Property.Subproperty 中设置属性 (， CancelVerb.Text 例如) 。
