UWP/C# 根据 NavView 模式更改控件可见性

Question

我需要尝试更改基于 NavigationView 的 StackPanel 的可见性 "PaneDisplaymode"

我有以下导航视图控件和一个简单的 AppBarButton StackPanel。

我不确定是否有办法引用当前的 PanDisplayMode 然后确定 StackPanel 的可见性？

关于此的任何 guidance/help 都很棒。

<NavigationView IsSettingsVisible="False" 
                            PaneTitle="Menu"                            
                            x:Name="NavView"                             
                            IsBackButtonVisible="Collapsed" 
                            PaneDisplayMode="Left" 
                            AlwaysShowHeader="True"        
                            SelectionChanged="NavView_SelectionChanged">            

            <!-- All navigation view Items nested within here -->
            <NavigationView.MenuItems>

                <StackPanel Orientation="Horizontal" UseLayoutRounding="False" x:Name="AppBarButtons" Tag="AppBarButtonPanel"> <!--Visibility="{Binding ControlShit}"-->
                    <AppBarButton Icon="Page2" Margin="0, 2, 1, 0" Tag="New_Sheet" HorizontalAlignment="Center" Width="56.5" Height="56.5" ClickMode="Press" Click="NewFile_ClickAsync"/>
                    <AppBarButton Icon="OpenFile" Margin="1, 2, 0, 0" Tag="Open_Sheet" HorizontalAlignment="Center" Width="56.5" Height="56.5" ClickMode="Press" Click="OpenFile_Click"/>
                    <AppBarButton Icon="Save" Margin="1, 2, 0, 0" Tag="Save_Sheet" HorizontalAlignment="Center" Width="56.5" Height="56.5" ClickMode="Press" Click="SaveButton_ClickAsync"/>
                    <AppBarButton Icon="Setting" Margin="1, 2, 0, 0" Tag="Settings_Page" HorizontalAlignment="Center" Width="56.5" Height="56.5" ClickMode="Press" Click="SettingsButton_Click"/>
                    <AppBarButton Icon="Calculator" Margin="1, 2, 0, 0" Tag="Calculator_Open" HorizontalAlignment="Center" Width="56.5" Height="56.5" ClickMode="Press" Click="CalcButton_ClickAsync"/>
                </StackPanel>
</NavigationView.MenuItems>

Answer 1

您可以使用PaneClosed and PaneOpened events of NavigationView to change the Visibility of your StackPanel , another way to do it would be to use DisplayModeChanged，其中您可以使用PaneDisplayMode 属性的switch语句并检查它是关闭还是打开，然后更改相应的可见性。
