The textbox control does not display when used as an Adorner

The textbox control does not display when used as an Adorner。Replacing the textbox with a textblock or button control will display it normally。

Avalonia version：11.1.3
operating system：windows10

test code:
var text = new TextBox(); //TextBlock
text.Text = "asdfasdfsdf";
text.Background = Brushes.Red;
text.Width = 10;
text.Height = 10;

AdornerLayer.SetAdorner(this, text);
AdornerLayer.SetIsClipEnabled(text, false);

Sorry, I'm not very good at operating GitHub

I can only repro when trying to adorn a Window (which may or may not be a supported use case). The adorner shows for any other case I've tried: a UserControl that creates + attaches the adorner to itself and creating+attaching the adorner to a child StackPanel.

Can you create a minimal repro and post the project?

I'm sorry

Because my custom panel is incorrect, the textbox is not displaying. I will study again. Thank you

A new problem has been discovered.
The TestText Box control inherits from the Text Box and does not display when using it as a decorator. I have created a test project, thank you
test.zip

@maoyy Hi, that file does not exist.

If you're inheriting a control, you need to ensure you provide a ControlTheme for it or use StyleKeyOverride so that it uses the ControlTheme of the parent. Otherwise, it has no visual.

Thank you
I uploaded the project, but I don't know why it hasn't.
I used StyleKeyOverride，I'll stick out the code。

test code:

public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();

    var testPanel = new TestPanel();
    testPanel.Width = 600;
    testPanel.Height = 500;

    this.Content = testPanel;
}

}

public class TestPanel : Panel
{
public TestPanel()
{
Background = Brushes.Red;

    var testControl = new TestControl();
    testControl.Width = 200;
    testControl.Height = 200;

    this.Children.Add(testControl);
}

}

public class TestControl : Control
{
public TestControl()
{
this.PointerEntered += TestControl_PointerEntered;
}
public override void Render(DrawingContext context)
{
context.DrawRectangle(Brushes.Transparent, new Pen(Brushes.Black, 1), new Rect(0, 0, Width, Height));
}
private void TestControl_PointerEntered(object? sender, Avalonia.Input.PointerEventArgs e)
{
var text = new TextBox();//TextBox
text.Text = "asdfasdfsdf";
text.PointerExited += Text_PointerExited;

    AdornerLayer.SetAdorner(this, text);
    AdornerLayer.SetIsClipEnabled(text, false);
}
private void Text_PointerExited(object? sender, Avalonia.Input.PointerEventArgs e)
{
    AdornerLayer.SetAdorner(this, null);
}

}

public class TestTextBox : TextBox
{
protected override Type StyleKeyOverride => base.StyleKeyOverride;
public TestTextBox() { }
}

thank you very much
