C#Silverlight 3 - 以编程方式在页面之间导航？

Question

假设我有一个带有多个页面的C#Silverlight 3应用程序.第一页称为Home,第二页称为Details.导航到详细信息的唯一方法是以编程方式.我该怎么做呢？!到处寻找答案,我发现的都是xaml uri mapper实现....

非常感谢

Answer 1

你试过NavigationService吗？

this.NavigationService.Navigate(new Uri("Details.xaml",UriKind.Relative));

Answer 2

C#:

this.navContent.Navigate(new Uri("Welcome", UriKind.Relative));

XAML:

<navigation:Frame
    x:Name="navContent"
    HorizontalContentAlignment="Stretch"
    VerticalContentAlignment="Stretch"
    Source="Welcome">
    <navigation:Frame.UriMapper>
        <uriMapper:UriMapper>
            <uriMapper:UriMapping Uri="Welcome" MappedUri="/Views/Welcome.xaml" />
            <uriMapper:UriMapping Uri="Profile" MappedUri="/Views/Profile.xaml" />
            <uriMapper:UriMapping Uri="Details/{id}" MappedUri="/Views/Details.xaml?photoid={id}" />
        </uriMapper:UriMapper>
    </navigation:Frame.UriMapper>
</navigation:Frame>

甚至你的"细节"页面也应该被映射(尽管你说的是.)

Answer 3

C#App.Current.Host.NavigationState ="/ Welcome";

XAML

Answer 4

最好的解决方案是:

将此代码添加到App.xaml.cs:

private static Grid root;

private void Application_Startup(object sender, StartupEventArgs e)
{
    root = new Grid();
    root.Children.Add(new MainPage());

    this.RootVisual = root;
}

public static void Navigate(UserControl newPage)
{
    UserControl oldPage = root.Children[0] as UserControl;

    root.Children.Add(newPage);
    root.Children.Remove(oldPage);
}

然后,要在页面之间导航,您只需调用:

App.Navigate(new OtherSamplePage());
