Question

我正在为UWP项目创建多区域演示者。所以我使用Split View创建了汉堡菜单的AppShell文件。有AppShellFrame所以每个页面都显示在这个框架中。但我想显示右侧面板进行设置，所以我添加了第二个分割视图并设置PanePlacement="Right"以显示右侧，并添加了另一个称为PasscodeFrame的帧。

在第二个分割视图中，我设计了设置视图布局并添加了设置密码的切换按钮。当切换按钮切换时，我想在PasscodeFrame的右侧面板中显示PasscodeView.xaml。我在以下链接中阅读了有关多区域的所有内容：

http://depblog.weblogs.us/2015/11/23/mvvmcross-uwp-splitview/

我按照所有步骤操作，但在AppShellFrame中打开的密码视图不在PasscodeFrame中。我在后面的代码中添加了以下PasscodeView的类定义：

[MvxRegion（＆＃34; PasscodeFrame＆＃34）]

我已经声明了这样的app框架：

public Frame AppFrame => AppShellFrame;

所以我认为每个页面都在AppShellFrame中打开。所以我的问题是如何在PasscodeFrame中打开密码视图？我已经使用过MvxRegion，但它不适用于我。以及如何为右侧面板维护后挡？

这是我的代码：

AppShell.xaml

<base:BaseView

    <!-- Top-level navigation menu + app content -->
    <SplitView x:Name="RootSplitView" DisplayMode="CompactInline" OpenPaneLength="280" IsTabStop="False">
        <SplitView.Pane>
            <Grid Background="{ThemeResource Background100OffWhiteBrush}">
                <Grid.RowDefinitions>
                    <RowDefinition />
                    <RowDefinition Height="Auto" />
                </Grid.RowDefinitions>

                <!-- A custom ListView to display the items in the pane.  The automation Name is set in the ContainerContentChanging event. -->

                <!-- MAIN MENU ITEMS -->
                <controls:NavMenuListView x:Name="FeedsList"

                    <!-- ACTION MENU ITEMS -->
                    <controls:NavMenuListView.Footer>

                    </controls:NavMenuListView.Footer>

                </controls:NavMenuListView>
            </Grid>
        </SplitView.Pane>

        <SplitView.Content>
            <!-- OnNavigatingToPage we synchronize the selected item in the nav menu with the current page.
             OnNavigatedToPage we move keyboard focus to the first item on the page after it's loaded. -->
            <Frame x:Name="AppShellFrame"
               Margin="0"
               Navigating="OnNavigatingToPage" Navigated="OnNavigatedToPage"
               Background="White">
                <Frame.ContentTransitions>
                    <TransitionCollection>
                        <NavigationThemeTransition>
                            <NavigationThemeTransition.DefaultNavigationTransitionInfo>
                                <EntranceNavigationTransitionInfo />
                            </NavigationThemeTransition.DefaultNavigationTransitionInfo>
                        </NavigationThemeTransition>
                    </TransitionCollection>
                </Frame.ContentTransitions>
            </Frame>
        </SplitView.Content>
    </SplitView>

   <!-- HAMBURGER MENU -  Declared last to have it rendered above everything else, but it needs to be the first item in the tab sequence. -->
    <ToggleButton x:Name="TogglePaneButton"
        Margin="0"
        TabIndex="1" 
        Checked="{x:Bind CheckTogglePaneButtonSizeChanged}"

        IsChecked="{Binding IsPaneOpen, ElementName=RootSplitView, Mode=TwoWay}"
        AutomationProperties.Name="Menu" ToolTipService.ToolTip="Menu"
        Style="{StaticResource SplitViewTogglePaneButtonStyle}"/>

    <!-- Right Side Panel -->
    <SplitView PanePlacement="Right" x:Name="uiRightSideSplitView">

        <SplitView.Pane>
            <!--Setting View-->
             <ToggleSwitch Toggled="PasscodeToggleSwitch_Toggled" HorizontalAlignment="Stretch" Width="400" Header="passcode enabled"/>
        </SplitView.Pane>

        <SplitView.Content>
            <Frame x:Name="PasscodeFrame" >
            </Frame>
        </SplitView.Content>
    </SplitView>               
</Grid>

AppShell.xaml.cs

public sealed partial class AppShell : BaseView

  public AppShell()
    {
        this.InitializeComponent();

   private void PasscodeToggleSwitch_Toggled(object sender, RoutedEventArgs e)
    {
       // Here Setting view model call passcode view model and it open in AppShellFrame. But I want to open in PasscodeFrame.

       SettingViewModel.PasscodeEnabled = true;

    }

}

PasscodeView.xaml.cs

[MvxRegion（＆＃34; PasscodeFrame＆＃34）]

public sealed partial class PasscodeView：BaseView

{

#region Constructor

public PasscodeView()
{
    InitializeComponent();
    this.Loaded += onLoaded;

    // Set navigation cache mode disabled, So each time create new instance of view and view model
    NavigationCacheMode = NavigationCacheMode.Disabled;
}

}
