Is there a TreeDataGrid control compatible with Avalonia 12?

[nil4]

The Avalonia 12.0.0-preview1 release seems to be incompatible with Avalonia.Controls.TreeDataGrid.

Steps to reproduce

Create a new project with Avalonia 12.0.0-preview1 packages, reference latest TreeDataGrid control per docs -- including the <StyleInclude> in App.axaml.

The project compiles successfully but crashes at runtime:

System.MissingMethodException: Method not found: 'Avalonia.Data.IBinding Avalonia.Markup.Xaml.MarkupExtensions.DynamicResourceExtension.ProvideValue(System.IServiceProvider)'.

   at Avalonia.ClassicDesktopStyleApplicationLifetimeExtensions.StartWithClassicDesktopLifetime(AppBuilder builder, String[] args, Action`1 lifetimeBuilder)
   at Repro.Program.Main(String[] args) in ~/Repro/Program.cs:line 9

The stack trace points to the TreeDataGrid style reference, namely:

<StyleInclude Source="avares://Avalonia.Controls.TreeDataGrid/Themes/Fluent.axaml"/>

Is there any TreeDataGrid package compatible with 12.0 available for testing?

The open-source TreeDataGrid control has been deprecated and is now pulled into Avalonia Accelerate for future development (https://avaloniaui.net/accelerate/tree-data-grid).

No maintainers stepped up for the open source version of the control and the new closed-source control will supersede it's features soon: #19653

You have three options:

1. Use Avalonia Accelerate's TreeDataGrid -- they will soon update for Avalonia 12 previews. There is a community edition now as well.
2. Pull the TreeDataGrid source code into your project and tweak what you need in order to get it to work with Avalonia 12. This is probably the recommended approach for existing applications/code and there shouldn't be much difficulty -- more just re-compile. I would consider this a temporary solution though.
3. Fork the control and start a new community maintained version compatible with latest versions of Avalonia.

I believe I had tested package version 11.3.1 which I assume is already under the new license, but unfortunately appears to be incompatible.

That's true, hence the question.. Which package is compatible? 🙂

I told you here: #20748 (comment)

The open-source TreeDataGrid has been dropped. It is no longer maintained and hasn't been compiled for 12.x previews. I gave you solutions.

I do appreciate it. The doc I was referring to (and testing with) is https://docs.avaloniaui.net/accelerate/components/treedatagrid/quickstart -- I did note accelerate in that URL and to be clear, I was not asking about earlier open-source versions of the control (though I'm aware of its history.)

The accelerate controls needs to be compiled for 12.0 but currently they are not. There is some more work to do beforehand. But it is on the todo list, no worries.

Thank you for your understanding.

I have my own fixed version if you need right now, but its different package: https://www.nuget.org/packages/TreeDataGrid/12.0.0-preview1
