Set focus on a control when Window is loaded with WinUI 3

Question

I want to set focus to a textbox user control when the window is loaded.

I've tried putting txtLogin.Focus(FocusState.Programmatic); in the constructor

I've also tried doing something like

    void MainWindow_Activated(object sender, WindowActivatedEventArgs e)
    {
      txtLogin.Focus(FocusState.Programmatic);
    }

What am I missing?

Try the Loaded event:

public MainWindow()
{
    this.InitializeComponent();

    this.txtLogin.Loaded += (s, e) =>
    {
        this.txtLogin.Focus(FocusState.Programmatic);
    };
}
