extjs folder is lost解决方法 和 FineUI主题切换时 iframe内的内容主题不变的解决方法

错误原因：extjs包和FineUI版本不一致 或者是 webconfig配置中 没有设置为任何人可访问  解放方法下载和FineUI版本相同的extjs包就ok了

解决方法：FineUI主题切换时 iframe内的内容主题不变的解决方法：窗体继承 PageBase页面

PageBase页面代码：

public class PageBase : System.Web.UI.Page

    {

        #region OnInit



        protected override void OnInit(EventArgs e)

        {

            if (!IsPostBack)

            {

                if (PageManager.Instance != null)

                {

                    HttpCookie themeCookie = Request.Cookies["Theme_v4"];

                    if (themeCookie != null)

                    {

                        string themeValue = themeCookie.Value;

                        PageManager.Instance.Theme = (Theme)Enum.Parse(typeof(Theme), themeValue, true);



                        //if (IsSystemTheme(themeValue))

                        //{

                        //    PageManager.Instance.Theme = (Theme)Enum.Parse(typeof(Theme), themeValue, true);

                        //}

                        //else

                        //{

                        //    PageManager.Instance.CustomTheme = themeValue;

                        //}

                    }



                    HttpCookie langCookie = Request.Cookies["Language_v4"];

                    if (langCookie != null)

                    {

                        string langValue = langCookie.Value;

                        PageManager.Instance.Language = (Language)Enum.Parse(typeof(Language), langValue, true);

                    }

                }

            }



            base.OnInit(e);

        }



        private bool IsSystemTheme(string themeName)

        {

            themeName = themeName.ToLower();

            string[] themes = Enum.GetNames(typeof(Theme));

            foreach (string theme in themes)

            {

                if (theme.ToLower() == themeName)

                {

                    return true;

                }

            }

            return false;

        }



        #endregion
