我遇到了 asp.net 的字段验证器在我的页面上占用空间的问题。我四处搜索，文档说使用 Display="Dynamic" 来防止验证器占用空间。但是，当我使用它时，总是会显示错误消息。

我究竟做错了什么？

我只想在用户单击“保存”按钮或失去对文本框的关注时显示错误消息。而且我不希望验证器占用空间。 

     <p>Please enter a new email:</p> 
     <asp:TextBox runat="server" MaxLength="255" ID="TextBoxEmail" />

     <asp:RequiredFieldValidator ID="RequiredFieldValidator1"  
          ValidationGgroup="Email" 
          ErrorMessage="Please enter an email" 
          ControlToValidate="TextBoxEmail" runat="server"></asp:RequiredFieldValidator>

     <asp:RegularExpressionValidator ID="RegularExpressionValidator2" 
         ValidationGroup="Email"
          ControlToValidate="TextBoxEmail"                    
          ErrorMessage="Please enter valid email"
          runat="server"      
          ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" />


      <p>Please re-enter your email:</p> 
      <asp:TextBox runat="server" ID="TextBoxEmail2" />


      <asp:LinkButton ValidationGroup="Email" runat="server" Text="Save"  OnClick="linkbuttonSave_Click"  />

Only thing I notice in your code is you have a typo in ValidationGgroup="Email". It should be ValidationGroup="Email"

Other than that, Display="Dynamic" works for me.

After clicking, submit button -

<p>
    Please enter a new email:</p>
<asp:TextBox runat="server" MaxLength="255" ID="TextBoxEmail" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" ValidationGroup="Email"
    ErrorMessage="Please enter an email" ControlToValidate="TextBoxEmail" runat="server"
    Display="Dynamic"></asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="RegularExpressionValidator2" ValidationGroup="Email"
    ControlToValidate="TextBoxEmail" ErrorMessage="Please enter valid email" runat="server"
    ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" Display="Dynamic" />
<p>
    Please re-enter your email:</p>
<asp:TextBox runat="server" ID="TextBoxEmail2" />
<asp:CompareValidator ID="PasswordCompare" runat="server" ControlToCompare="TextBoxEmail"
    ControlToValidate="TextBoxEmail2" CssClass="failureNotification" Display="Dynamic"
    ErrorMessage="Must match." ValidationGroup="Email"></asp:CompareValidator>
<asp:RequiredFieldValidator ID="RequiredFieldValidator3" ValidationGroup="Email"
    ErrorMessage="Please enter an confirm email" ControlToValidate="TextBoxEmail2" runat="server"
    Display="Dynamic"></asp:RequiredFieldValidator>
<asp:LinkButton ID="LinkButton1" ValidationGroup="Email" runat="server" Text="Save"
    OnClick="linkbuttonSave_Click" />

您可以将属性 Display 设置为“Dynamic”或“none”，第二个将导致错误消息仅显示在验证摘要中。

我通过删除 "ValidationGroup=.." 让它工作得很好。Havent查看了它的作用，但没有它它工作得很好，并且不确定为什么需要它（假设验证器控件具有电子邮件文本框的控件ID）
