unoplatform / uno.windowscommunitytoolkit

The Windows Community Toolkit is a collection of helper functions, custom controls, and app services. It simplifies and demonstrates common developer tasks building UWP apps for Windows 10. The toolkit is part of the .NET Foundation.

Uno Platform port of Windows Community Toolkit

This port allows for Uno Platform based apps to use Windows Community Toolkit for WinUI 3 on Windows, iOS, macOS, Android, WebAssembly and Linux.

See below on this page for information about UWP.

The following packages are available:

• Uno.CommunityToolkit.Common
• Uno.CommunityToolkit.WinUI
• Uno.CommunityToolkit.WinUI.Connectivity
• Uno.CommunityToolkit.WinUI.DeveloperTools
• Uno.CommunityToolkit.WinUI.UI
• Uno.CommunityToolkit.WinUI.UI.Animations
• Uno.CommunityToolkit.WinUI.UI.Behaviors
• Uno.CommunityToolkit.WinUI.UI.Controls
• Uno.CommunityToolkit.WinUI.UI.Controls.Core
• Uno.CommunityToolkit.WinUI.UI.Controls.DataGrid
• Uno.CommunityToolkit.WinUI.UI.Controls.Input
• Uno.CommunityToolkit.WinUI.UI.Controls.Layout
• Uno.CommunityToolkit.WinUI.UI.Controls.Markdown
• Uno.CommunityToolkit.WinUI.UI.Controls.Media
• Uno.CommunityToolkit.WinUI.UI.Controls.Primitives
• Uno.CommunityToolkit.WinUI.UI.Media

Using the Uno Platform Windows Community Toolkit packages

These packages are providing support for the Uno Platform supported targets (iOS, Android, macOS, WebAssembly and Skia GTK/WPF/Tizen).

On Windows projects (the WinUI 3 Desktop head), please install the official Windows Community Toolkit packages for WinUI 3.

If you are building a library, use the following to conditionally include the toolkit builds:

<ItemGroup Condition="$(TargetFramework.Contains('windows10'))">
	<PackageReference Include="CommunityToolkit.WinUI.Controls" Version="7.1.2" />
</ItemGroup>
<ItemGroup Condition="!$(TargetFramework.Contains('windows10'))">
	<PackageReference Include="Uno.CommunityToolkit.WinUI.Controls" Version="7.1.200" />
</ItemGroup>

For example, using the default Uno template, you only need to add the following lines (as needed) to the class library <AppName>.csproj. No changes are needed in each target separately (<AppName>.Wasm.csproj, <AppName>.Windows.csproj, etc.)

<ItemGroup Condition="$(TargetFramework.Contains('windows10'))">
  <PackageReference Include="CommunityToolkit.Common" />
  <PackageReference Include="CommunityToolkit.WinUI" />
  <PackageReference Include="CommunityToolkit.WinUI.Connectivity" />
  <PackageReference Include="CommunityToolkit.WinUI.DeveloperTools" />
  <PackageReference Include="CommunityToolkit.WinUI.UI" />

<ItemGroup Condition="!$(TargetFramework.Contains('windows10'))">
  <PackageReference Include="Uno.CommunityToolkit.Common" />
  <PackageReference Include="Uno.CommunityToolkit.WinUI" />
  <PackageReference Include="Uno.CommunityToolkit.WinUI.Connectivity" />
  <PackageReference Include="Uno.CommunityToolkit.WinUI.DeveloperTools" />
  <PackageReference Include="Uno.CommunityToolkit.WinUI.UI" />
  <PackageReference Include="Uno.CommunityToolkit.WinUI.UI.Animations" />
  <PackageReference Include="Uno.CommunityToolkit.WinUI.UI.Behaviors" />

TokenizingTextbox crashing on Android

Describe the bug

I've added a TokenizingTextbox to a page and it works as expected on UWP. On Android it accepts input but after a while (presumably while trying to convert my word into a token) it bring a long native stacktrace (see attachment), blocks the application and finaly crashes the application.

Steps to Reproduce

1. Add a TokenizingTextBox to a page like this:

<Page
    x:Class="NutzMich.Pages.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:NutzMich"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"     xmlns:xamarin="http://uno.ui/xamarin"
    xmlns:toolkit="using:Uno.UI.Toolkit" xmlns:controls="using:Microsoft.Toolkit.Uwp.UI.Controls"
    mc:Ignorable="d">

    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <controls:TokenizingTextBox Grid.Row="0"></controls:TokenizingTextBox>
</Grid>
</Page>

2. Run the application on Android
3. Enter a word, hit space or enter
4. Stacktrace appears and app quits after some seconds

Expected behavior

The TokenizingTextBox works on Android like expected.

DataGrid : Freezes iOS or MacCatalyst app when added to visual tree

Current behavior

CommunityToolkit.WinUI.UI.Controls.DataGrid will freeze an iOS (Simulator or Device) or MacCatalyst app when added to the visual tree of the app.

NOTES:

• no issues with the following platforms:
  • Android
  • WASM
  • Skia.Wpf
  • Skia.Gtk
  • MacOS

Expected behavior

DataGrid can be added to Uno.WinUi app as it can on other platforms.

How to reproduce it (as minimally and precisely as possible)

1. Create new UnoApp
2. Build, deploy and launch app to iOS Simulator or Device
3. Click [Click to add DataGrid] button
4. Notice app freezes on _grid.Children.Add(_dataGrid); in the following block of code:

        private void _button_Click(object sender, RoutedEventArgs e)
        {
            if (_dataGrid is null)
            {
                _dataGrid = new CommunityToolkit.WinUI.UI.Controls.DataGrid();

                var list = new List<string> { "apple", "butter", "cranberries", "dessert", "eggs", "fish" };
                _dataGrid.ItemsSource = list;
                _dataGrid.AutoGenerateColumns = true;

                Grid.SetRow(_dataGrid, 1);
                _grid.Children.Add(_dataGrid);
            }
        }

Workaround

Have not yet tested if the issue is present in the following scenarios:

• Deploy to iOS Local Device from vs4win 2022 (I'm having an issue with this as well)
• Build and manually deploy from vs4mac (I would try that later today)

Works on UWP/WinUI

Is there a "how to build and debug" document or video (maybe an old Twitch stream) for the UNO.WCT project? A quick glance at the code made me realize it was going to be a career to get to the point where I could start debugging this.

TextBoxRegex doesn't work within a TabViewItem

this alone in a page works:

<StackPanel>
                    <TextBox Header="Nom" Text="{Binding Nom, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                         extensions:TextBoxRegex.Regex="{x:Bind NomRegex}"
                         extensions:TextBoxRegex.ValidationMode="Forced" 
                         Background="{Binding (extensions:TextBoxRegex.IsValid), RelativeSource={RelativeSource Self}, Converter={StaticResource ValidationConverter}}"
                         Style="{StaticResource InputStyle}"/>
                    <Button Content="OK"/>
                </StackPanel>

but put into a TabViewItem and the TextBoxRegex stops working:

<custom:TabView>
        <custom:TabView.Items>
            <custom:TabViewItem Header="Info">
                <StackPanel>
                    <TextBox Header="Nom" Text="{Binding Nom, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                         extensions:TextBoxRegex.Regex="{x:Bind NomRegex}"
                         extensions:TextBoxRegex.ValidationMode="Forced" 
                         Background="{Binding (extensions:TextBoxRegex.IsValid), RelativeSource={RelativeSource Self}, Converter={StaticResource ValidationConverter}}"
                         Style="{StaticResource InputStyle}"/>
                    <Button Content="OK"/>
                </StackPanel>
            </custom:TabViewItem>
        </custom:TabView.Items>
    </custom:TabView>

with:

public class ValidationConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, string language) => (bool)value ? new SolidColorBrush(Colors.PaleGreen) : new SolidColorBrush(Colors.OrangeRed);
        public object ConvertBack(object value, Type targetType, object parameter, string language) => throw new NotImplementedException();
    }

private string NomRegex { get; } ="^.{2,}$";

Add `CursorProperty`

Currently it's not included:

Uno.WindowsCommunityToolkit/CommunityToolkit.WinUI.UI/Extensions/FrameworkElement/FrameworkElementExtensions.Mouse.cs

Line 11 in 60d9964

#if !HAS_UNO

Note that the implementation is using CoreWindow.PointerCursor, which I think only supported on Wasm currently.

So I think we can add CursorProperty back and make it effectively a no-op for platforms other than Wasm.

HamburgerMenu doesn't work on Droid (bombs app).

I'm submitting a...

Bug report (I searched for similar issues and did not find one)

Current behavior

UWP HamburgerMenu works (from Microsoft.Toolkit...). However, Droid + Uno.Microsoft.Toolkit, compiles, deploys, but bombs immediately on display of the xaml. (logcat cannot connect). Without the HamburgerMenu, the app functions.

Expected behavior

function with HamburgerMenu

ColorPicker has issues on WASM

Describe the bug

Couple of issues with the display of the ColorPicker on WASM (not sure if only when displayed in ColorPickerButton)

1. Color Palette grid doesn't display.
2. Sliders don't display until manipulated:

Didn't test the square picker tab (had it disabled in my scenario).

Steps to Reproduce

                          <controls:ColorPickerButton>
                            <controls:ColorPickerButton.ColorPickerStyle>
                                <Style TargetType="controls:ColorPicker">
                                    <Setter Property="IsAlphaEnabled" Value="False" />
                                    <Setter Property="IsColorSpectrumVisible" Value="False" />
                                    <Setter Property="IsColorPaletteVisible" Value="True" />
                                    <Setter Property="IsColorChannelTextInputVisible" Value="True" />

[Feature] Unsigned assembiles?

Describe the problem this feature would solve

I'm using .NET Framework a Uno Platform application, that uses the DataGrid control. However, the application always crashes when initializing the DataGrid as Uno.UI is not strongly-named (a strongly-named assembly is required. (Exception from HRESULT: 0x80131044).

Describe the solution

Either:

• Strongly Name Uno Platform assemblies (which Jérôme Laban said you won't)?
• Release special unsigned builds for use with .NET Framework WPF applications.

Describe alternatives you've considered

Currently I'm cloning your source code and directly reference the project but it's a maintenance burden compared to nuget packages.

Additional context & Screenshots

I'm really using MasterDetailsView

It's a VERY useful control.

1. Add a MasterDetailsView
2. Bind it to a collection
3. Add ItemTemplate and DetailsTemplate with x:DataType bound to your ViewModel
4. Run the app - the DetailsTemplate is not rendered

Expected behavior

The DetailsTemplate gets rendered as it is on UWP.

How can I add UNO.CommunityToolkit.WinUI to the .NET 6 project?

Hi!

I'm writing an open source app, using WinUI 3 and now trying to run it on the other platforms through the UNO Platfrom.
I've segregated the functionality on the different layers (class libraries).
I'm referencing the CommunityToolkit.WinUI library from the library project with target framework net6.0-windows10.0.22000.0
Now I want to connect such project to the .NET6.0 Linux and MacOS app. It's impossible, because of framework differences.
So I'm trying to add one more target framework - .NET 6 to the library.
And the only one conflict, that I have - is CommunityToolkit.WinUI library.

Is it possible to solve it using UNO.CommunityToolkit.WinUI?

[Question] Is it possible to use the CommunityToolkit with Uno.WinUI?

I'm developing a WinUI 3 app and on Windows there is already a preview for the CommunityToolkit targeting the WinUI 3.
I'd like to know if your porting of the CommunityToolkit can be used with Uno.WinUI or if I need to wait for a specific version

Please port Microsoft.Toolkit.Uwp.UI.Extensions

Adding MenuItems to NavigationView causes an exception (+out of memory for visualstate)

I'm submitting a... Bug report

Current behavior

Adding MenuItems to a NavigationView causes an exception. (Without menu items, the area is blank (no hamburger menu), but doesn't bomb).
Oddly, adding a VisualStateManager (as recommended on https://docs.microsoft.com/en-us/windows/uwp/design/controls-and-patterns/navigationview), causes an Out of Memory Exception (below).

Code including MenuItems that cause an exception

    <Grid Background="Silver">
        <NavigationView x:Name="NavigationViewControl" >
            <NavigationView.MenuItems>
                <NavigationViewItem Content="A" x:Name="A" />
                <NavigationViewItem Content="B" x:Name="B" />
                <NavigationViewItem Content="C" x:Name="C" />
            </NavigationView.MenuItems>
        </NavigationView>
    </Grid>

Adding a VisualStateManager pushes it to Out of Memory...

<Grid >
    <VisualStateManager.VisualStateGroups>
        <VisualStateGroup>
            <VisualState>
                <VisualState.StateTriggers>
                    <AdaptiveTrigger MinWindowWidth="{x:Bind NavigationViewControl.CompactModeThresholdWidth}" />
                </VisualState.StateTriggers>

                <VisualState.Setters>
                    <Setter Target="NavigationViewControl.PaneDisplayMode" Value="Top"/>
                </VisualState.Setters>
            </VisualState>
        </VisualStateGroup>

[Wasm] Infinite measure with PivotPanel

I'm submitting a...

• Bug report (I searched for similar issues and did not find one)

Current behavior

When navigating to any sample on wasm, the sample page fails to load:

System.InvalidOperationException: PivotPanel-278753: Invalid measured size [1910;Infinity]. NaN or Infinity are invalid desired size.

Expected behavior

The sample page should load without error.

Minimal reproduction of the problem with instructions

Try to navigate navigate to any of the sample, like: Controls -> AlignmentGrid).

Uno Carousel control is not working properly

Describe the bug

I wasn't able to make a carousel to work on ios, android and uwp:
[iOS] - Not able to swipe
[Android] - Control does not show up.
[UWP] - App does not build, got this error: Xaml Internal Error error WMC9999: Type universe cannot resolve assembly: Uno.UI, Version=255.255.255.255, Culture=neutral, PublicKeyToken=null.
while Uno UI is added to the project.

Steps to Reproduce

CarouselTestA.zip

Steps to reproduce the behavior:

Run the attached solution on ios, android and windows and see that it doesn't work properly.

Expected behavior

Control works same as in the windows sample app from Windows Apps Store: https://apps.microsoft.com/store/detail/windows-community-toolkit-sample-app/9NBLGGH4TLCQ?hl=en-ca&gl=CA

Re-enable the ImageCropper control

Describe the problem this feature would solve

In the original Uno WCT post https://platform.uno/blog/uno-platform-support-for-the-windows-community-toolkit/
it mentions that
Some notable parts of the toolkit are not working at the moment:
Windows Composition APIs samples, for which the Uno Platform only has very limited support on iOS only.

I've had a quick look at reintroducing the ImageCropper here:
https://github.com/edparitor/Uno.WindowsCommunityToolkit

I progressed to the point that it's no longer using Win2d and is loading a sample image, but I've realised that the last parts are down to the composition API - at least I think they are.

I've also seen that composition api may be on the 3.1 roadmap
unoplatform/uno#670

Describe the solution

Wait for composition API to be implemented and revisit

Describe alternatives you've considered

Re-implement the image cropper in a completely different way for uno - possibly making more use of skia

Additional context & Screenshots

Expander crashes the app.

ResourceNameToResourceString converter does not find the resource altough it exists.

Describe the bug

Using the converter to obtain a named resource provokes a NullReferenceException in WindowsCommunityToolkit and an empty string in the Uno.WindowsCommunityToolkit.

Steps to Reproduce

Launch the attached solution in Windows head, a NullReferenceException should be thrown after MainPage.InitializeComponent() is executed. If the xaml with the Converter is commented it does not throw.
Launch the attached solution in WPF/Wasm head, a TextBlock with "Hello World", should be seen. The TextBlock which is using the Converter shows an empty string..

The resource is defined in Strings/en/Resources.resw and the same resource name is in a property of the code-behind of MainPage.xaml and x:binded to the Text property of the TextBlock.

Expected behavior

No error should be produced and the string resource should be set to the TextBlock.

note: If you attach the assignment to a button handler. Tapping a first time will make the columns to be generated, and tapping it again will cause the rows to be shown.

workaround:

	public static DependencyProperty DelayedItemsSourceProperty { get; } = DependencyProperty.RegisterAttached(
		"DelayedItemsSource",
		typeof(IEnumerable),
		typeof(DataGridExtensions),
		new PropertyMetadata(default, (d, e) => d.Maybe<DataGrid>(control => OnDelayedItemsSourceChanged(control, e))));

	public static IEnumerable GetDelayedItemsSource(DataGrid obj) => (IEnumerable)obj.GetValue(DelayedItemsSourceProperty);
	public static void SetDelayedItemsSource(DataGrid obj, IEnumerable value) => obj.SetValue(DelayedItemsSourceProperty, value);

	#endregion

	private static void OnDelayedItemsSourceChanged(DataGrid sender, DependencyPropertyChangedEventArgs e)
	{
		// DataGrid not showing rows with initial values, only "late" provided values are displayed somehow...
		// This is the workaround for that:
		_ = RunOnUIThread(() => sender.ItemsSource = (IEnumerable)e.NewValue);
	}

	private static async Task RunOnUIThread(Action action)
	{
		await CoreApplication.MainView.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
		{
			action();
		});
	}
}

for databinding, just bind to that attached property instead of ItemsSource.
for code-behind, just call SetDelayedItemsSource during OnLoaded like so:

Task.Run(() => DataGridExtensions.SetDelayedItemsSource(dg, items));

[Question] No non-prerelease packages?

I tried finding the Uno WCT ports in the NuGet package manager but wasn't able to since I didn't check the "Include prerelease" checkbox. This left me wondering if there is a reason for this and if this can be pointed out in the readme file maybe since people might not notice that and think there is no Uno WCT port available on NuGet or something else might be broken.

The adaptivegrid control is visible in uwp apps, but not in android and wasm.

Describe the bug

Hello

Added Page to Shared project and AdaptiveGridView.
When executed in UWP, the output is normally displayed on the page. However, when I target and launch the Android app and WASM, the controls are not visible.
Is it normal that it does not appear to be a prerelease?

• Is this bug a regression in the toolkit? If so, what toolkit version did you last see it work:

Steps to Reproduce

Steps to reproduce the behavior:

1. Add a page.
2. Add an AdaptiveGrid control.
3. Bind to ItemsSource and add ItemTemplate.
4. Run UWP as the target. (Control outputs normally)
5. Run Android as a target. (Control not visible)

Expected behavior

A clear and concise description of what you expected to happen.
Control visible
