ValidationSummary 控件

ValidationSummary控件是用于显示验证所有验证错误摘要的控件，当我们将验证控

件的 Display属性设置 None 的时候，验证错误信息就在这里显示。

ValidationSummary控件有三个常见属性：

属性名	说明
DisplayMode	指定显示模式，有 BulletList、 List、 SingleParagraph 三种模式
ShowMessageBox	是否以客户端提示框的信息显示验证错误信息摘要
ShowSummary	是否在网页中采用内联方式显示错误摘要

下面是一个ValidationSummary 控件的例子（在使用 ValidationSummary控件的

时候一定要将验证控件的 Display 属性设为 None）：
