推荐答案

您的页面不提交，因为该按钮时要点击将鼠标移动到下了。这是因为它获得焦点和验证-的ErrorMessage消失到左边。
如果插入＆LT; BR /方式＆gt; 在它工作的按钮前

Your page does not submit because the button moves away under the mouse when you want to click it. This is because it gets focus and the Validator-ErrorMessage disappears to the left. If you insert a <br/> in front of the button it works.

通常情况下，我使用*作为文本和使用的ValidationSummary 来显示的ErrorMessage（S）：

Normally i use * as Text and use a ValidationSummary to display the ErrorMessage(s):

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
        ControlToValidate="TextBox1" Display="Dynamic" 
        ErrorMessage="This is the Errormessage" Text="*"></asp:RequiredFieldValidator>
<asp:Button ID="Button1" runat="server" Text="Submit" />
<asp:ValidationSummary ID="ValidationSummary1" runat="server" />

或者，如果使用ASP.Net Ajax的，你可以用漂亮的控制像的 ValidatorCalloutExtender 。
