尝试一下，

try this,

< asp:dropdownlist id ="ddl1" runat ="server" xmlns:asp =#unknown">
< asp:listitem> me
< asp:listitem>其他
< asp:listitem>选择


< asp:requiredfieldvalidator id ="rfv1" runat ="server" controltovalidate ="ddl1" initialvalue ="select" xmlns:asp =#unknown">
ErrorMessage =请提供必填字段">

< cc1:validatorcalloutextender id ="v1" runat ="server" targetcontrolid ="rfv1" xmlns:cc1 =#unknown">

<asp:scriptmanager id="Scriptmanager1" runat="server" xmlns:asp="#unknown">

<asp:dropdownlist id="ddl1" runat="server" xmlns:asp="#unknown">
<asp:listitem>me
<asp:listitem>others
