WinUI: How to change NavigationView.Header background color?

Question

I have a NavigationView and would like to change the header background color:

I have tried:

• Looking in generic.xaml for likely styles to override
• Using a HeaderTemplate

Here's my code:

<NavigationView Background="Gray">
    <NavigationView.Header>
        <Border Background="Green">
            <TextBlock Text="Header"/>
        </Border>
    </NavigationView.Header>
    <Border Background="Orange">
        <TextBlock Text="Sweet content"/>
    </Border>
</NavigationView>

Answer 1

Try to override the NavigationViewContentBackground theme resource:

<NavigationView Background="Gray">
    <NavigationView.Resources>
        <SolidColorBrush x:Key="NavigationViewContentBackground" Color="Red" />
    </NavigationView.Resources>
    <NavigationView.Header>
        <Border Background="Green">
            <TextBlock Text="Header"/>
        </Border>
    </NavigationView.Header>
    <Border Background="Orange">
        <TextBlock Text="Sweet content"/>
    </Border>
</NavigationView>
