Question

验证

Answer 1

http://msdn.microsoft.com/zh-cn/library/system.web.ui.webcontrols.validationsummary.showmessagebox(v=vs.90).aspx
<asp:ValidationSummary 
     id="valSum" 
     DisplayMode="BulletList"
     ShowMessageBox="true"
     ShowSummary="false" 
     HeaderText="You must enter a value in the following fields:"
     Font-Names="verdana" 
     Font-Size="12"
     runat="server"/>

Answer 2

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="-请输入内容" ControlToValidate="TextBox1"  Text="*"></asp:RequiredFieldValidator>
把ControlToValidate="TextBox1"改成ControlToValidate="TextBox2"

Answer 3

有没有引入jquery??好像2012还是2010开始,用验证控件需要引入Jquery,同时还需要引用"AspNet.ScriptManager.jQuery.dll"

Answer 4

<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
 
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="-请输入内容" ControlToValidate="TextBox1"  Text="*"></asp:RequiredFieldValidator>
 
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click"/>
 
<asp:ValidationSummary ID="ValidationSummary1" runat="server" ShowMessageBox="true" ShowSummary="false"  EnableClientScript="true"/>
最后一个为什么少了ControlToValidate属性？我给你标红了
