How to get the ItemContainer from itemsview winui3

[Strypper]

I notice that ItemsView return a pure object model type instead of Container like Listview, I need to grab the UI to grab the UI element => prepare connected animation

[Strypper]

I made the Forward connected animation working with this

    private void Section2ItemRepeater_ItemInvoked(Microsoft.UI.Xaml.Controls.ItemsView sender, Microsoft.UI.Xaml.Controls.ItemsViewItemInvokedEventArgs args)
    {
        var selectedCard = args.InvokedItem as ProfileCardModel;
        if (selectedCard is null)
            return;

        var elementToAnimate = FindElementByTag(this, selectedCard.Id) as UIElement;
        if (elementToAnimate is null)
            return;

        ViewedItem = selectedCard;

        ConnectedAnimationService.GetForCurrentView().PrepareToAnimate("ForwardConnectedAnimation", elementToAnimate);
        Detail.Parameter pageParameter = new(selectedCard.Id, selectedCard.ImagePath);
        Frame.Navigate(typeof(Detail.Page),
              pageParameter,
              new SlideNavigationTransitionInfo()
              {
                  Effect = SlideNavigationTransitionEffect.FromRight
              });
    }
    private UIElement FindElementByTag(DependencyObject root, string tag)
    {
        int count = VisualTreeHelper.GetChildrenCount(root);
        for (int i = 0; i < count; i++)
        {
            DependencyObject child = VisualTreeHelper.GetChild(root, i);

            if (child is FrameworkElement element && element.Tag?.ToString() == tag)
                return element as UIElement;

            var result = FindElementByTag(child, tag);
            if (result != null)
                return result;
        }
        return null;
    }

But I can not make it work with Back navigation simply TryStartConnectedAnimationAsync and ScrollIntoView is not available for the ItemsView

[Strypper]

Oh I actually don't need to depend on the TryStartConnectedAnimationAsync to animate I can actually do this

    private async void Section2ItemRepeater_Loaded(object sender, RoutedEventArgs e)
    {
        if (ViewedItem is null || ViewedUIElement is null)
            return;

        ConnectedAnimation animation = ConnectedAnimationService.GetForCurrentView().GetAnimation("BackConnectedAnimation");
        if (animation is null)
            return;

        animation.TryStart(ViewedUIElement);
    }

    private void Section2ItemRepeater_ItemInvoked(Microsoft.UI.Xaml.Controls.ItemsView sender, Microsoft.UI.Xaml.Controls.ItemsViewItemInvokedEventArgs args)
    {
        var selectedCard = args.InvokedItem as ProfileCardModel;
        if (selectedCard is null)
            return;

        var elementToAnimate = FindElementByTag(this, selectedCard.Id) as UIElement;
        if (elementToAnimate is null)
            return;

        ViewedItem = selectedCard;
        ViewedUIElement = elementToAnimate;

        ConnectedAnimationService.GetForCurrentView().PrepareToAnimate("ForwardConnectedAnimation", elementToAnimate);
        Detail.Parameter pageParameter = new(selectedCard.Id, selectedCard.ImagePath);
        Frame.Navigate(typeof(Detail.Page),
              pageParameter,
              new SlideNavigationTransitionInfo()
              {
                  Effect = SlideNavigationTransitionEffect.FromRight
              });
    }
