当我单击 RadioButton 时，我需要进行回发，以便它可以运行我的 RadioButton 代码。（AutoPostback="true"）。我在 jQuery UI 对话框中有我的单选按钮，当我单击该按钮时没有任何反应，并且出现错误：

未捕获的 Sys.WebForms.PageRequestManagerServerErrorException：Sys.WebForms.PageRequestManagerServerErrorException：处理服务器上的请求时发生未知错误。服务器返回的状态码是：404

我读到一些对话框实际上将自己置于表单之外？我将此添加到我的 Javascript 函数中以防止它：

function getFiles(canDo) {
        //create Popup with content from div
        $('#file').dialog({//file is the div where my controls are
            autoOpen: true,
            height: 'auto',
            width: 'auto',
            modal: true,
            buttons: {
                "Ok": function () {
                    debugger;

                },
                Cancel: function () {
                    $(this).dialog('close');

                }
            }
        });
        $('#file').appendTo($("form:first"));
    }

关于为什么它不会成功回发的任何想法？或者为什么我得到那个错误？

我的控制：
