                                    ＆LT;输入类型=复选框ID =1值=1/＆GT;
                                    ＆LT;标签=1＆GT;＆LT; /标签＆gt;
                                ＆LT; /李＆GT;
                                 ＆LT;立GT;
                                     ＆LT;跨度类=textDropdown＆GT;文本1＆LT; / SPAN＆GT;
                                    ＆LT;输入类型=复选框ID =2值=2/＆GT;
                                    ＆LT;标签=2＆GT;＆LT; /标签＆gt;
                                ＆LT; /李＆GT;
                                 ＆LT;立GT;
                                     ＆LT;跨度类=textDropdown＆GT;文本1＆LT; / SPAN＆GT;
                                    ＆LT;输入类型=复选框ID =3值=3/＆GT;
                                    ＆LT;标签=3＆GT;＆LT; /标签＆gt;
                                ＆LT; /李＆GT;
                                 ＆LT;立GT;
                                     ＆LT;跨度类=textDropdown＆GT;文本1＆LT; / SPAN＆GT;
                                    ＆LT;输入类型=复选框ID =4值=4/＆GT;
                                    ＆LT;标签=4＆GT;＆LT; /标签＆gt;
                                ＆LT; /李＆GT;
                            ＆LT; / UL＆GT;
                        ＆LT; / DIV＆GT;
 

解决方案

添加属性 =服务器您的复选框。这会让他们的服务器端控件，并允许使用ASP.NET的ViewState保存其状态。

请注意，您可能需要更改复选框的标识（和标签有关）目前是你喜欢的数字1，你必须让他们如字母C1。

                                </li>
                            </ul>
                        </div>

解决方案

Add attribute runat="server" to your checkboxes. This will make them server-side controls and allow to use ASP.NET ViewState to save their states.

Note that you may have to change IDs of the checkboxes (and related for labels) currently yours are numeric like "1", you will have to make them alphanumeric e.g. "C1".
