仅显示一个带有RequiredFieldValidator 的字段。

您需要使用在运行时创建 html 的 asp.net 服务器端控件。

例如，您可以使用：

<asp:textbox ID='phonenumber' runat='server'/>
<asp:RequiredFieldValidator ID="ValidateName"
     ControlToValidate="phonenumber"                        
     runat="server" ErrorMessage="Phone Number is required is Required"
     Display=Dynamic>
</asp:RequiredFieldValidator>
