一.silverlight与silverlight中可以利用委托（delegate）来刷新frame.Refresh()

1.在子类中定义委托捕捉关闭事件按钮

 1         public delegate void onCloseClick(object sender, RoutedEventArgs e);
 2         public onCloseClick onclose;
 3         private void CancelButton_Click(object sender, RoutedEventArgs e)
 4         {
 5             if (onclose != null)
 6             {
 7                 onclose(sender, e);
 8             }
 9             this.Visibility = Visibility.Collapsed;
10         }

2.在frame所在的页面中利用委托来调用frame.refresh()方法

 List<Button> listButton = ShowOpenPanelConfig(tb);
                Child_YJCBS yjcb = new Child_YJCBS();
                OPPanel op = EasySL.Controls.Window.ShowOpPanel("一键出表", yjcb, this.floatePanel, txtMsgInfo);
                op.onclose += (s, e) => { ContentFrame.Refresh(); };
                yjcb.onclose += (s, e) =>
                {
                    op.Visibility = Visibility.Collapsed; ContentFrame.Refresh();
                };
View Code

二、利用aspx中的cookie来控制sl中的定时器
1.在frame所在的页面中定义计时器

 1  private void TimeInitData()
 2         {
 3             if (myDispatcherTimer != null)
 4                 myDispatcherTimer.Stop();
 5             //创建计时器      
 6             myDispatcherTimer = new System.Windows.Threading.DispatcherTimer();
 7             //创建间隔时间     
 8             myDispatcherTimer.Interval = new TimeSpan(0, 0, 0, 5);
 9             //创建到达间隔时间后需执行的函数    
10             myDispatcherTimer.Tick += (ss, ee) =>
11             {
12                 this.ContentFrame.Refresh();
13                 String[] cookies = HtmlPage.Document.Cookies.Split(‘;‘);
14                 foreach (String cookie in cookies)
15                 {
16                     String[] keyValues = cookie.Split(‘=‘);
17                     {
18                         if (keyValues[0].Trim() == "FirCookieKey")
19                         {
20                             myDispatcherTimer.Stop();
21                         }
22                     }
23                 }
24 
25             };
26             myDispatcherTimer.Start();
27         }

2.在aspx页面中创建cookie并设置cookie的过期时间

 1  if (isSuccess)
 2             {
 3                 Response.Cookies.Clear();
 4                 HttpCookie MyCookie = new HttpCookie("FirCookieKey");
 5                 MyCookie.Value = http://www.mamicode.com/"NewCookieValue";
 6                 MyCookie.Expires =DateTime.Now.Add(TimeSpan.FromMinutes(0.2));
 7                 HttpContext.Current.Response.Cookies.Add(MyCookie);
 8                 Server.Transfer("PreviewReport.aspx");
 9                 //Page.Response.Write("<script language=javascript>alert(\" 插入成功!\");</script>");
10             }

注意：以上设置的cookie过期时间为12秒，而sl是已5秒中的加载一次，
