【筆記】UserControl作為Ajax的請求結果

網上有很多，最初好像是看老趙的，我只不過寫成靜態了：

        public static string AsyncLoadControl<T>(string virtualPath,Action<T> act) where T : UserControl
        {
            Page p = new Page();
            T uc = (T)p.LoadControl(virtualPath);
            act(uc);
            p.Controls.Add(uc);
            StringWriter writer = new StringWriter();
            HttpContext.Current.Server.Execute(p, writer, false);
            return writer.ToString();
        }
        public static string AsyncLoadControl(string virtualPath)
        {
            Page p = new Page();
            Control uc =p.LoadControl(virtualPath);
            p.Controls.Add(uc);
            StringWriter writer = new StringWriter();
            HttpContext.Current.Server.Execute(p, writer, false);
            return writer.ToString();
        }

調用：

           //傳參

           string result = PageHelper.AsyncLoadControl<StrongTest.UC.News>("~/UC/News.ascx",
                            uc =>
                            {
                                uc.PageSize = 5;
                                uc.PageIndex = 1;
                            });           //不用傳參
           string result = PageHelper.AsyncLoadControl("~/UC/Comments.ascx");
