Silverlight 中Xaml页面跳转方式

来源：互联网发布：灌南县农村淘宝编辑：程序博客网时间：2024/05/19 09:51

可以先在App.xaml后台代码中定义一个对象：
Grid rootGrid = new Grid();
同时在App.xaml后台代码中新增一个方法：
////////////////
/// <summary>
/// 页面跳转
/// </summary>
/// <param name="usercontrol"></param>
public static void RedirectTo(UserControl usercontrol)
{
App app = (App)Application.Current;
app.rootGrid.Children.Clear();
app.rootGrid.Children.Add(usercontrol);
}
然后以后的Xaml页面直接通过以下方式处理：
App.RedirectTo(new MyXXXaml());

例如：
namespace SilverLight_My
{
     public partial class App : Application
     {
           public App()
          {

                 this.Startup += this.Application_Startup;
                 this.UnhandledException += this.Application_UnhandledException;

                InitializeComponent();
         }

         private void Application_Startup(object sender, StartupEventArgs e)
         {
               this.RootVisual = rootGrid;

         }

        /// <summary>
        /// 页面跳转
        /// </summary>
        /// <param name="usercontrol"></param>
        public static void RedirectTo(UserControl usercontrol)
       {
              App app = (App)Application.Current;
              app.rootGrid.Children.Clear();
              app.rootGrid.Children.Add(usercontrol);
       }
   }
}
