ItemTemplate

Now that we've set up the host control, we can have a look at the ChildChanged event that we mentioned; this is where we set up the UWP control (rather than the host control):

private Windows.UI.Xaml.Controls.TreeView? _tvFoundBooks = null;
private void windowsXamlHostTreeView_ChildChanged(object? sender, EventArgs e)
{
    if (sender == null) return;
 
    var host = (WindowsXamlHost)sender;
    _tvFoundBooks = (Windows.UI.Xaml.Controls.TreeView)host.Child;
    _tvFoundBooks.ItemInvoked += _tvFoundBooks_ItemInvoked;
    _tvFoundBooks.ItemsSource = DataSource;
 
    const string Xaml = "<DataTemplate xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"><TreeViewItem ItemsSource=\"{Binding Children}\" Content=\"{Binding Name}\"/></DataTemplate>" ...
