c# - 链接按钮未在 asp.net 中回发

Question

直到昨天，我已经把很多linkbutton东西放在一个网络表单上，一切正常。但现在我的 ajax 扩展器无法正常工作并且linkbuttons正在回发。我的一些代码是

 <table  width="460px">
    <tr>
        <td colspan="2" 
            style=" color: #C48239; font-style: normal; font-size: 18px; font-family: 'Bookman Old Style'; text-align:center;height:22px;">
           Manage Your Profile</td>
    </tr>

Answer 1

您在应用程序中是否有任何验证控件，通过将 Cause validation = false 设置为链接按钮控件来检查一次。

Answer 2

有时您的系统已更改为旧时（例如一年前），链接按钮也不会重定向

Answer 3

应用程序内部可能有验证控件，通过设置 Cause validation = false 来检查一次链接按钮控件。
