如何：自定义 PasswordRecovery 控件

2014-10-22

更新：2007 年 11 月

可以使用以下方法自定义 PasswordRecovery 控件：

可以编辑显示的模板并更改控件的用户界面 (UI)。
可以将 ASP.NET 主题应用到该控件。有关更多信息，请参见 ASP.NET 主题和外观概述。
可以使用控件的属性（如 QuestionLabelText 或 InstructionTextStyle）修改其外观。有关详细信息，请参见类库参考中 PasswordRecovery 控件的属性。

该主题描述如何使用模板自定义 System.Web.UI.WebControls.PasswordRecovery 控件。

编辑 PasswordRecovery 模板

将一个 PasswordRecovery 控件添加到页面，如下面的代码示例所示。

<asp:PasswordRecovery ID="PasswordRecovery1" Runat="server">
</asp:PasswordRecovery>

您可以通过应用样式自定义 PasswordRecovery 控件的外观。使用属性（如 LabelStyle、HyperLinkStyle 和 TitleTextStyle 属性）可以将所有需要的样式应用到模板。

若要自定义 PasswordRecovery 控件的内容，请继续执行下面的步骤以修改 PasswordRecovery 控件所使用的模板。

创建一个 UserNameTemplate 模板以指定首次呈现控件时显示的标记和控件，如下面的代码示例所示。

安全说明：
该示例具有一个文本框，用于接受用户输入，这是一个潜在的安全威胁。默认情况下，ASP.NET 网页验证用户输入是否不包括脚本或 HTML 元素。有关更多信息，请参见脚本侵入概述。
