我在隐藏的 div 中有一个 C# Checkboxlist。div 在某些事件上显示，然后关闭。提交表单时，我尝试根据 checkboxlist.items 的选定值更新数据库位字段，但无论是否选中，它们总是返回 false。当包含项目的 div 被隐藏时，如何获取项目的选定值？

div 是我使用 jquery 显示/隐藏的对话框

 $(document).ready(function () {
        $('#<%=txtLANG.ClientID %>').click(function () {
            $("#overlay-back").dialog({
                resizable: false,
                modal: true,
                width: 500,
                height: 400,
                buttons: {
                    OK: function () {
                        GetLanguages();
                        $(this).dialog("close");
                    },
                    Cancel: function () {
                        $(this).dialog("close");
                    }
                }
            });
        });
    });

这是DIV ...代码隐藏只不过是根据复选框列表项的选定值将参数设置为真/假

<div id="overlay-back" style="display:none;">
        <table width="100%">
            <tr>
                <td width="50%">
                    <asp:CheckBox runat="server" ID="chkEnglish" TextAlign="Right" Text=" English" />
                    <div class="popup-container">
                            <img id="help_button_chkEnglish" class="help-button" src="/Images/help-button.png" alt="" />
                                <div class="help-popup hidden" id="help_popup_chkEnglish">
                                    <div class="popup-arrow-border"></div> <div class="popup-arrow"></div>

                        </div>
