AjaxPro问题

前台做了一个多文件上传功能 页面上放置了一个HTML的按钮控件
后台有一个函数public void Upfile()
{
 //遍历File表单元素
            HttpFileCollection files = HttpContext.Current.Request.Files;
            //状态信息
            StringBuilder strMsg = new StringBuilder();
            strMsg.Append("上传的文件分别是：<hr color='red'/>");
            try
            {
                for (int iFile = 0; iFile < files.Count; iFile++)
                {
                    //检查文件扩展名字
                    HttpPostedFile postedFile = files[iFile];
                    string fileName, fileExtension;
                    fileName = Path.GetFileName(postedFile.FileName);
                    if (fileName != "")
                    {
                        try
                        {
                            string strpath = System.Web.HttpContext.Current.Request.MapPath("~/ResourcesFolder/") + fileName;
                            if (System.IO.File.Exists(strpath))
                            {
                                Response.Write("已经存在文件：" + fileName + "<br>");
                                return;
                            }
                            else
                            {
                                Model.File mf = new Model.File();
                                BLL.NRBLL bn = new BLL.NRBLL();
                                Guid guid1 = Guid.NewGuid();
                                Guid guid2 = Guid.NewGuid();
                                Guid guid3 = Guid.NewGuid();
                                Guid guid4 = Guid.NewGuid();
                                mf.Fileid = guid1;
                                mf.Folderid = guid2;
                                mf.Filepath = strpath;
                                mf.FileSize = postedFile.ContentLength;
                                mf.Decription = postedFile.ContentType.ToString();
                                mf.CreateOn = DateTime.Now;
                                mf.CreateBy = guid3;
                                mf.ModefyOn = DateTime.Now;
                                mf.ModefyBy = guid4;
                                if (bn.FN_UploadRes(mf) > 0)
                                {
                                    Response.Write("文件上传成功：" + fileName + "<br>");
                                }
                                else
                                {
                                    Response.Write("文件上传失败：" + fileName + "<br>");
                                }
                                fileExtension = Path.GetExtension(fileName);
                                strMsg.Append("上传的文件类型：" + postedFile.ContentType.ToString() + "<br>");
                                strMsg.Append("客户端文件地址：" + postedFile.FileName + "<br>");
                                strMsg.Append("上传文件的文件名：" + fileName + "<br>");
                                strMsg.Append("上传文件的扩展名：" + fileExtension + "<br>");
                                strMsg.Append("上传文件的大小：" + postedFile.ContentLength.ToString() + "个字节" + "<br>");
                                //可根据 扩展名字的不同保存到不同的文件夹
                                //注意：可能要修改你的文件夹的匿名写入权限。
                                //保存上传文件内容
                                postedFile.SaveAs(System.Web.HttpContext.Current.Request.MapPath("~/ResourcesFolder/") + fileName);
                            }                        }
                        catch (Exception)
                        {                            throw;
                        }                    }
                }                strStatus.Text = strMsg.ToString();
            }
            catch (System.Exception Ex)
            {
                strStatus.Text = Ex.Message;
            }
}
那么我前台的这个HTML按钮如何触发它的onclick事件呢？我用WEB控件试过了 很容易 但是公司不允许用WEB控件 
如果用ajaxpro可以吗 这个是没有参数的
