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(); };
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 = "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，
