未拾取 asp.net Web 用户控件文本框值 - jquery fancybox

Question

我有一个包含两个表单的自定义 Web 控件。这些表单均包含一个用于提交表单的链接按钮。

当我尝试提交任一表单并追踪任何文本框的值时，这些值都是空的。如果我将“Text =“whatever””属性添加到文本框并重新测试，则会在跟踪测试中拾取并打印该值。

该控件是母版页的一部分，位于 之前。我假设它与回发序列有关，但现在已经研究了几个小时，并认为最好询问以前可能遇到过此问题的人。

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>

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