Dynamically-created menu items with commands do not work about avalonia

[LeftofZen]

Apologies, this does appear to work. The reason I didn't include Classes is because Intellisense did not like it and wouldn't autocomplete, and there were also issues with Items -> ItemsSource, but pasting it in does work. Thanks for the help!

The solution in #3100 still works, but your datatemplate content should not be menuitem. Otherwise your will have a menuitem inside menuitem.

Thankyou for the reply, but as I already mentioned, the solution in #3100 does not work. Please try it out yourself and see. Here is the full axaml code for it so you can verify yourself that it truly does not work:

<Window xmlns="https://github.com/avaloniaui"
		xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
		xmlns:vm="using:MenuItemCommandBug.ViewModels"
		xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
		xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
		mc:Ignorable="d" d:DesignWidth="256" d:DesignHeight="128"
		x:Class="MenuItemCommandBug.Views.MainWindow"
		x:DataType="vm:MainWindowViewModel"
		Icon="/Assets/avalonia-logo.ico"
Title="MenuItemCommandBug">

	<Menu>
		<MenuItem Header="Items" ItemsSource="{Binding Items}">
			<MenuItem.ItemTemplate>
				<DataTemplate>
					<MenuItem Header="{Binding Name}" Command="{Binding MenuCommand}" IsEnabled="True" Focusable="True"/>
				</DataTemplate>
			</MenuItem.ItemTemplate>
			<MenuItem.Styles>
				<Style Selector="MenuItem.SubItems MenuItem" x:DataType="vm:MenuItemModel">
					<Setter Property="Header" Value="{Binding Name}"/>
					<Setter Property="Command" Value="{Binding MenuCommand}"/>
				</Style>
			</MenuItem.Styles>
		</MenuItem>
	</Menu>
</Window>

On your other point:

but your datatemplate content should not be menuitem. Otherwise your will have a menuitem inside menuitem.

Notice ItemsSource="{Binding Items}" - this is how you make nested menu items. If you are confused about what this looks like visually, see this screenshot; these sub-menu items are not enabled when they should be.

The last thing you can do to convince yourself this is truly a bug is to remove the Command="{Binding MenuCommand}" from the axaml. The (sub) menu items are re-enabled again. This shows there is a bug in the interaction of menu items and commands.

I tried and replied. You didnt set Classes for your Parent MenuItem, thats why it does not work for you.
Classes="SubItems"
