How to display all installed fonts in a ComboBox

Question

I need to display all the user's installed fonts in a WinUI 3 ComboBox. I'm using this code:

<ComboBox x:Name="FontComboBox" ItemsSource="{Binding Source={x:Static Fonts.SystemFontFamilies}}">
    <ComboBox.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Source}" FontFamily="{Binding Source}" />
        </DataTemplate>
    </ComboBox.ItemTemplate>
</ComboBox>

But this causes the error:

The type 'x:Static' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

Not sure what an assembly reference is.

What would I do to fix this?

Answer 1

AFAIK, WinUI 3 doesn't support x:Static.

So, let me show you another way to achieve this using the Win2D NuGet package.

<Page
    x:Class="FontFamiliesExample.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:local="using:FontFamiliesExample"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:win2d="using:Microsoft.Graphics.Canvas.Text"
    Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"
    mc:Ignorable="d">

    <StackPanel>
        <ComboBox ItemsSource="{x:Bind win2d:CanvasTextFormat.GetSystemFontFamilies()}" />
    </StackPanel>
