How to change the color of AppBar button text

Question

I have an AppBar Button that I want to change the color of the text.

<Button Style="{StaticResource EditAppBarButtonStyle}" Click="Button_Click"  Foreground="White"/>

I can change the button color by Foreground="White" but that does not change the text color so how can I change the text?

Answer 1

You have to modify AppBarButtonStyle slightly. Currently the Foreground of text is default set as AppBarItemForegroundThemeBrush, but you can replace with TemplateBinding of Foreground. So use the below given style, so when will you set Foreground it will change foreground of button as well as the text below it.

<Style x:Key="AppBarButtonStyle" TargetType="ButtonBase">
    <Setter Property="Foreground" Value="{StaticResource AppBarItemForegroundThemeBrush}"/>
    <Setter Property="VerticalAlignment" Value="Stretch"/>
    <Setter Property="FontFamily" Value="Segoe UI Symbol"/>
    <Setter Property="FontWeight" Value="Normal"/>
    <Setter Property="FontSize" Value="20"/>
    <Setter Property="AutomationProperties.ItemType" Value="App Bar Button"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ButtonBase">
                <Grid x:Name="RootGrid" Width="100" Background="Transparent">
                    <StackPanel VerticalAlignment="Top" Margin="0,12,0,11">
                        <Grid Width="40" Height="40" Margin="0,0,0,5" HorizontalAlignment="Center">
                            <TextBlock x:Name="BackgroundGlyph" Text="&#xE0A8;" FontFamily="Segoe UI Symbol" FontSize="53.333" Margin="-4,-19,0,0" Foreground="{StaticResource AppBarItemBackgroundThemeBrush}"/>
                            <TextBlock x:Name="OutlineGlyph" Text="&#xE0A7;" FontFamily="Segoe UI Symbol" FontSize="53.333" Margin="-4,-19,0,0"/>
                            <ContentPresenter x:Name="Content" HorizontalAlignment="Center" Margin="-1,-1,0,0" VerticalAlignment="Center"/>
                        </Grid>

Answer 2

Overwriting the theme brush worked for me.

<SolidColorBrush x:Key="AppBarItemForegroundThemeBrush" Color="White"/>
