验证摘要控件不显示错误

Question

我真的不知道为什么会这样。验证摘要似乎是非常基本的控件。单击“提交”按钮后，各个错误消息会出现在字段旁边（例如，当需要字段时，文本框旁边会显示“需要字段”的错误消息），但在我的验证摘要处没有出现应该。我没有任何验证组，因为我想验证页面上的所有内容。我页面上的所有内容看起来都很好。我似乎无法弄清楚是什么可能阻止摘要显示。验证摘要位于页面顶部。这是我的代码：

<form id="form1" runat="server">

  <asp:ValidationSummary
  id="valSum" 
  DisplayMode="BulletList"
  runat="server"/>

<div id ="name">

您需要像这样在验证器中设置 ErrorMessage：

 <asp:RequiredFieldValidator ErrorMessage="Fist name is required" ...
