UWP從NavigationView刪除突出顯示

Question

我想從NavigationView菜單項中刪除突出顯示的內容

我如何才能使在某些MenuItems上突出顯示的內容不會移到該項目上？

Answer 1

您可以通過在App.xaml或放置NavigationView控件的頁面中添加以下代碼來簡單地覆蓋默認顏色資源。

在App.xaml中

 <Application.Resources>
    <SolidColorBrush x:Key="NavigationViewSelectionIndicatorForeground" Color="Transparent" />
</Application.Resources>

或存在NavigationView控件的頁面中

 <Page.Resources>
    <SolidColorBrush x:Key="NavigationViewSelectionIndicatorForeground" Color="Transparent" />
</Page.Resources>

根據您的要求，您可以修改 NavigationViewItem樣式，並將SelectionIndicator Rectangle的寬度設置為0。您也可以直接使用以下樣式。

<Style TargetType="NavigationViewItem">
    <Setter Property="Foreground" Value="{ThemeResource NavigationViewItemForeground}"/>
    <Setter Property="Background" Value="{ThemeResource NavigationViewItemBackground}"/>
    <Setter Property="BorderBrush" Value="{ThemeResource NavigationViewItemBorderBrush}"/>
    <Setter Property="BorderThickness" Value="{StaticResource NavigationViewItemBorderThickness}"/>
    <Setter Property="UseSystemFocusVisuals" Value="True"/>
    <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="NavigationViewItem">
                <Grid x:Name="LayoutRoot" Background="{TemplateBinding Background}" Height="40" Control.IsTemplateFocusTarget="True">
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="PointerStates">
                            <VisualState x:Name="Normal"/>
                            <VisualState x:Name="PointerOver">
                                <VisualState.Setters>
                                    <Setter Target="LayoutRoot.(RevealBrush.State)" Value="PointerOver"/>
                                    <Setter Target="LayoutRoot.Background" Value="{ThemeResource NavigationViewItemBackgroundPointerOver}"/>
                                    <Setter Target="RevealBorder.BorderBrush" Value="{ThemeResource NavigationViewItemBorderBrushPointerOver}"/>
                                    <Setter Target="ContentPresenter.Foreground" Value="{ThemeResource NavigationViewItemForegroundPointerOver}"/>
                                </VisualState.Setters>
                            </VisualState>
                            <VisualState x:Name="Pressed">
                                <VisualState.Setters>
                                    <Setter Target="LayoutRoot.(RevealBrush.State)" Value="Pressed"/>
                                    <Setter Target="LayoutRoot.Background" Value="{ThemeResource NavigationViewItemBackgroundPressed}"/>
                                    <Setter Target="RevealBorder.BorderBrush" Value="{ThemeResource NavigationViewItemBorderBrushPressed}"/>

                                </VisualState.Setters>
                            </VisualState>
                            <VisualState x:Name="PointerOverSelected">
