[regression/8.0.0-rc.1.9171] Unable to set Button TextColor

[imsam67]

Description

No matter what I do, I can't seem to set the TextColor for Button on iOS. Also, compared to .NET 7, FontSize seems over sized -- see comparison screenshot below.

I first started experiencing this with .NET 8 Preview 7. If I switch back to targeting .NET 7, everything goes back to normal.

I set the Button sytling in Styles.xaml which looks like this:

<Style TargetType="Button">
    <Setter Property="TextColor" Value="{StaticResource White}" />
    <Setter Property="TextTransform" Value="Uppercase" />
    <Setter Property="BackgroundColor" Value="{StaticResource UIGraphite}" />
    <Setter Property="FontFamily" Value="OpenSansRegular" />
    <Setter Property="FontSize" Value="10" />
    <Setter Property="FontAttributes" Value="Bold" />
    <Setter Property="CharacterSpacing" Value="1.5" />
    <Setter Property="CornerRadius" Value="12" />
    <Setter Property="Padding" Value="20,2" />
    <Setter Property="Shadow.Brush" Value="{StaticResource Gray600Brush}" />
    <Setter Property="Shadow.Offset" Value="10,10" />
    <Setter Property="Shadow.Opacity" Value="0.6" />
    <Setter Property="HeightRequest" Value="25" />
</Style>

I also tried overriding these settings by specifying TextColor in the Button control to no avail.

Steps to Reproduce

1. Use the style I provided for Button control
2. Target .NET 8 and run it
3. Target .NET 7 and run it

I created a new .NET MAUI app updated the Styles.xaml file to use the same styling -- what's posted here -- and got the same behavior, meaning the color and size are not applying correctly to Button control.

Here's all the code in that app:

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="Ingrid.Time.Views.Dashboard.DashboardPage"
             BackgroundColor="White"
             Title="Ingrid.Time">
    <VerticalStackLayout>
        <Label 
            Text="Welcome to my new appp"
            TextColor="Black"
            VerticalOptions="Center" 
            HorizontalOptions="Center"
            Margin="0,30,0,0"/>
        <Button
            Text="Submit"
            WidthRequest="350"
            Margin="0,20,0,0"/>
    </VerticalStackLayout>
</ContentPage>

And here's the entire Styles.xaml file, pretty vanilla, except for button section:

And here's what it looks like:

@samhouts there also seems to be a size issue. It just defaults to a size other than what I set in Styles.xaml

[StephaneDelcroix]

some of the styles are applied, some are not, so it's unlikely related to the style changes. it looks ok on maccatalyst (on main), I'm trying to repro on iOS

[cfree789]

Seeing the exact same issue. In some testing I did, it seems that CharacterSpacing is a property that is causing the issue. Once you set that value, the FontSize and TextColor properties are no longer correct (maybe FontFamily and other text related properties as well). Remove it, and all of the properties seem to be set properly after relaunching the app (not via Hot Reload).

Possibly related? #10293

[imsam67]

@cfree789 is right. Setting CharacterSpacing property of Button control is causing this issue. I removed the CharacterSpacing for Button in Styles.xaml everything worked fine. I then tried adding it at the control level instead of setting it in Styles.xaml and the problem came back. Thank you for figuring this out @cfree789

[StephaneDelcroix]

I can confirm the CharacterSpacing prevent setting the TextColor on iOS
