styled property not working on UserControl

[touhidurrr]

Describe the bug

same as above.

To Reproduce

// LoginView.axaml.cs
public static readonly StyledProperty<bool> TriggerProperty = AvaloniaProperty.Register<LoginView, bool>("Trigger");

public bool Trigger
{
    get => GetValue(TriggerProperty);
    set => SetValue(TriggerProperty, value);
}

// LoginView.axaml

As you can see there is no error or warning. However... When I try to build it....

0>LoginView.axaml(22,35): Error AVLN3000 : Unable to find the parent scope for AvaloniaProperty lookup Line 22, position 35.

I tried many things. But could not fix this issue.

Expected behavior

Build succeeds.

Avalonia version

11.1.0-beta2

OS

Windows

Additional context

Autocompletions work but build fails.

You can only use TemplateBinding inside of the actual template. In your UserControl code you don't have any templates (from what I can see here).

So, you probably need:

IsVisible="{Binding $parent[ns:LoginView].Trigger}"

where "ns:LogingView" - is this user control.

Alternatively, you can add x:Name on your LoginView root element, and then use named control binding "{Binding #MyLoginView.Trigger}"

@maxkatz6 this is off-topic but can you answer this also... In login view after login is done I want to set trigger to false and make login invisible. How can I do it?

I'd swap views tbh. See Avalonia.Spamples for a simple Navigation sample
