Xaml style setter doesn't work

[n2-holden]

Is there something special I need to do to get Styles to work? I have a simple Style:

        <Grid.Resources>
            <Style TargetType="AppBarButton" x:Name="MenuStyle">
                <Setter Property="Foreground" Value="White" />
            </Style>
        </Grid.Resources>

Then, in the Grid I have:

        <AppBarButton Icon="World" Label="Companies" BorderThickness="2" Click="Click_Dashboard" Tag="Companies" />

The Foreground property doesn't get set in any of the AppBarButton. I also tried explicitly specifying a style as a StaticResource, but that doesn't even compile.

If you want to change styles you have to options, the first with implicit styles (without x:Name or x:Key), the second with explicit style (with an x:Name or x:Key). You can have more details in Microsoft's WinUI documentation about styles.

Here sample you can experiment with: https://playground.platform.uno/#9c23d023

<ContentControl>
    <FrameworkElement.Resources>
        <Style TargetType="AppBarButton">
            <Setter Property="Foreground" Value="Orange" />
        </Style>
        <Style TargetType="AppBarButton" x:Key="OtherStyle">
            <Setter Property="Foreground" Value="Red" />
        </Style>
    </FrameworkElement.Resources>

    <StackPanel>
        <AppBarButton Icon="World" Label="Companies" BorderThickness="2" Tag="Companies" />
        <AppBarButton Icon="World" Label="Others" BorderThickness="2" Tag="Companies" Style="{StaticResource OtherStyle}" />
    </StackPanel>
</ContentControl>
