C# 未拾取asp.net web用户控件文本框值-jquery fancybox

我有一个自定义web控件，它包含两个表单。这些表单都包含一个用于提交表单的链接按钮

当我尝试提交任何一个表单并跟踪任何文本框的值时，这些值都是空的。如果我在文本框中添加一个“Text=”whather“”属性并重新测试，那么该值将在跟踪测试中提取并打印出来

此控件是母版页的一部分，位于

前面。我假设它与回发序列有关，但我已经玩了几个小时了，我想最好问问以前可能遇到过这种情况的人

控件的代码：

<div style="display: none;">
<div id="LoginRegisterModal" style="width:auto;height:360px;overflow:auto;">

        <fieldset style="float:left; width:200px;">
        <legend>Register</legend>
        <p>Enter your email address below to register with us</p><br />
        <div>
                <asp:TextBox runat="server" ID="txtRegisterUsername" />

                <br />
                <asp:TextBox runat="server" ID="txtRegisterPassword" TextMode="Password" />
        </div>

        <asp:LinkButton Text="Register" runat="server" ID="btnRegister" OnCommand="btnLogin_Click" CommandArgument="Register" CssClass="registerButton" />

        <br />
        </fieldset>  

        <fieldset style="float:left; width:200px; margin-left:10px;">
        <legend>Login</legend>
        <p>Enter your email address below to login</p><br />
        <div>
                <asp:TextBox runat="server" ID="txtLoginUsername" />
                <br />
                <asp:TextBox runat="server" ID="txtLoginPassword" TextMode="Password" />
        </div>

        <asp:LinkButton Text="Login" runat="server" ID="btnLogin" CssClass="loginButton" OnCommand="btnLogin_Click" CommandArgument="Login" />

        <br />
        </fieldset>
        <div style="clear:both; float:left;"></div>        
</div>

原来这是一个与fancybox和asp.net相关的问题--

<script type="text/javascript">
    $(document).ready(function () {
        $(".loginregister").fancybox({
            'titlePosition': 'inside',
            'transitionIn': 'none',
            'transitionOut': 'none'
        });
    });
</script>
