ValidationSummary.ShowSummary 属性

定义

获取或设置一个值,该值指示是否内联显示验证摘要。

public:
 property bool ShowSummary { bool get(); void set(bool value); };
[System.ComponentModel.Bindable(true)]
public bool ShowSummary { get; set; }
public bool ShowSummary { get; set; }
[<System.ComponentModel.Bindable(true)>]
member this.ShowSummary : bool with get, set
member this.ShowSummary : bool with get, set
Public Property ShowSummary As Boolean

属性值

属性

示例

下面的代码示例演示如何使用 ShowMessageBoxShowSummary 属性来指定验证摘要同时显示在消息框中和网页上。

重要

此示例具有一个接受用户输入的文本框,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含脚本或 HTML 元素。 有关详细信息,请参阅脚本侵入概述

注解

除了 属性之外, ShowMessageBox 还可以使用此属性来控制验证摘要的显示位置。 如果此属性设置为 true,则会在网页上显示验证摘要。

注意

如果 和 ShowSummary 属性都ShowMessageBox设置为 true,则验证摘要将显示在消息框和网页上。
