Question

我在我的应用中包含了splitview。但我不知道如何填写我的splitview的内容。我读过我应该将框架嵌套在那里。所以我有我的Mainpage.xaml，如果用户点击一个菜单按钮，则splitview的内容应该是例如helpandabout.xaml。或者我应该在内容属性中嵌套什么？我如何用不同的页面替换内容。 我目前只是试图改变网格的可见性，如果用户按下一个按钮，但这不是这个控件背后的哲学。像这样：

<Grid x:Name="Grid1" Visibility="Visible"> </Grid>
<Grid Visibility="Collapsed" x:Name="Grid2"> </Grid>

并且用户按下splitview窗格上的按钮，代码执行此操作：

Grid1.Visibility = Visibility.Collapsed;
Grid2.Visibility = Visibility.Visible;

我知道这是一段愚蠢的代码。

实际上，您可以使用SplitView和创建导航等替换完整的App标准。

我所做的是以下内容：

1-从这里学习导航示例： uwp navigation example

2.-在你了解它是如何工作之后，它有一些技巧，比如命令栏在appbar之外，等等。你可以提取库中的所有代码。

AppShell.xaml，NavMenuItem，NavMenuListView.cs，PageHeader.xaml

3.-创建以下扩展名：

public class NavigationExtensions
{

public static void Initialize<T>(List<NavMenuItem> list, NavigationFailedEventHandler OnNavigationFailed, LaunchActivatedEventArgs e)
    {
        AppShell shell = Window.Current.Content as AppShell;

        // Do not repeat app initialization when the Window already has content,
        // just ensure that the window is active
        if (shell == null)
        {
            // Create a AppShell to act as the navigation context and navigate to the first page
            shell = new AppShell();

            shell.NavigationList = list;

            try
            {
                shell.CurrentItem = list.First(i => i.DestPage == typeof(T));
            }
            catch
            {

            }

            // Set the default language
            shell.Language = Windows.Globalization.ApplicationLanguages.Languages[0];

            shell.AppFrame.NavigationFailed += OnNavigationFailed;

            if (e.PreviousExecutionState == ApplicationExecutionState.Terminated)
            {
                //TODO: Load state from previously suspended application
            }
        }

        // Place our app shell in the current Window
        Window.Current.Content = shell;

        if (shell.AppFrame.Content == null)
        {
            // When the navigation stack isn't restored, navigate to the first page
            // suppressing the initial entrance animation.

            shell.AppFrame.Navigate(typeof(T), e.Arguments, new Windows.UI.Xaml.Media.Animation.SuppressNavigationTransitionInfo());
        }

        // Ensure the current window is active
        Window.Current.Activate();
    }

}

4.-在项目和App.xaml.cs中添加

引用所有这些内容

protected override void OnLaunched(LaunchActivatedEventArgs e)
    {
        NavigationExtensions.Initialize<PersonalView>(Navigation.GetNavigationMenuItems(),OnNavigationFailed,e);
    }

例如，方法是：

public class Navigation
{
    public static List<NavMenuItem> GetNavigationMenuItems()
    {
        var list = new List<NavMenuItem>(
        new[]
        {
            new NavMenuItem()
            {
                Symbol = Symbol.Contact,
                Label = "Personal",
                DestPage = typeof(PersonalView)
            },
            new NavMenuItem()
            {
                Symbol = Symbol.World,
                Label = "Countries",
                DestPage = typeof(CountriesView)
            },
            new NavMenuItem()
            {
                Symbol = Symbol.Setting,
                Label = "Settings",
                DestPage = typeof(SettingsView)
            },
        });

        return list;
    }
}

Splitview内容属性窗口通用
