Удаление анимации при наведении на NavigationMenuItem

Question

Я хотел бы удалить анимацию при наведении, которая отображается в пунктах меню навигации в меню навигации UWP.Я посмотрел вокруг, но не могу найти стиль по умолчанию для NavigationMenuItem.Не говоря уже о том, что создание совершенно нового стиля для чего-то, что должно быть несколько тривиальным, кажется излишним.Любые советы о том, как этого можно достичь?

Answer 1

Вы можете отредактировать стиль, как сказано в предыдущем ответе.

Или, возможно, просто установить BorderThickness в 0 следующим образом:

<NavigationView >
    <NavigationView.MenuItems>
        <NavigationViewItem BorderThickness="0" Content="Item1"/>
        <NavigationViewItem BorderThickness="0" Content="Item2"/>
    </NavigationView.MenuItems>
</NavigationView>

Answer 2

Это стиль NavigationViewItem .Вы можете изменить PointerOver VisualState , чтобы изменить анимацию при наведении.

<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

                        Background="{TemplateBinding Background}"
                        Control.IsTemplateFocusTarget="True">
