ComboBox does not dynamically change text

Hello! I’m using translation files for my application. I denote the translated string as follows: <v:String x:Key="Key">(Here is the translation)</v:String>. Also, changing the application language changes dynamically, that is, you do not have to restart.

If I change the language, the text remains in the settings. But when I open the ComboBox, everything is fine.

I also noticed that if you use DynamicResource for pages, the first selected item will not be displayed at all. We have to use StaticResource for the first element. This works with the normal style too, I’ve tested.

Avalonia version: 0.10.0-preview2 This problem was encountered in previous versions.

Please tell me what this might be related to?

Okay, at least I found a workaround.

1. Add a new class which provides the requested resource. We will listen to resource changes inside.

    public class ResourceProvider : ReactiveObject
    {
        public ResourceProvider(string key)
        {
            App.Current.GetResourceObservable(key).BindTo(this, x => x.Value);
        }

        [Reactive]
        public string Value { get; set; }  
    }

1. In our MainViewModel we add a list of Items:

    public MainWindowViewModel()
    {
        _languageManager = new(new CultureInfo("ru-RU"));

        foreach (var lang in _languageManager.Languages)
            LangItems.Add(new LangItem(lang));

        _selectedLangIndex = _languageManager.Languages.IndexOf(_languageManager.CurrentLanguage);

+        Items.Add(new ResourceProvider("VaueFirst"));
+        Items.Add(new ResourceProvider("VaueSecond"));
    }

+  public List<ResourceProvider> Items { get; } = new();

1. and now change the ComboBox like this

  <ComboBox SelectedIndex="0" 
+           Items="{Binding Items}">
+     <ComboBox.ItemTemplate>
+         <DataTemplate>
+             <TextBlock Text="{Binding Value}" />
+         </DataTemplate>
+     </ComboBox.ItemTemplate>
</ComboBox>

Result:

Hope it helps a bit. I still think the issue needs to be solved one day.
