ItemsView Horizontal Scrolling with Mouse Scroll Wheel

[DominicMaas]

Is this supported?

I've tried messing around with the base ScrollView, but no luck so far:

GalleryItemsView.ScrollView.ScrollPresenter.ContentOrientation = ScrollingContentOrientation.Horizontal;

GalleryItemsView.ScrollView.ScrollPresenter.HorizontalScrollMode = ScrollingScrollMode.Enabled;
GalleryItemsView.ScrollView.ScrollPresenter.VerticalScrollMode = ScrollingScrollMode.Disabled;

GalleryItemsView.ScrollView.ContentOrientation = ScrollingContentOrientation.Horizontal;

GalleryItemsView.ScrollView.HorizontalScrollMode = ScrollingScrollMode.Enabled;
GalleryItemsView.ScrollView.VerticalScrollMode = ScrollingScrollMode.Disabled;

<ItemsView.Layout>
    <StackLayout Orientation="Horizontal" Spacing="4" />
</ItemsView.Layout>

I should note that I'm running this code in the Loaded method of ItemsView as the base ScrollView is not exposed to xaml

You can simply do this:

// Register event after checking ScrollView is not null
ItemsView.ScrollView.PointerWheelChanged += ScrollView_PointerWheelChanged;

private static void ScrollView_PointerWheelChanged(object sender, PointerRoutedEventArgs e)
{
    if (sender is ScrollView { ComputedVerticalScrollMode: ScrollingScrollMode.Disabled, ComputedHorizontalScrollMode: ScrollingScrollMode.Enabled } scrollView)
        _ = scrollView.AddScrollVelocity(new(e.GetCurrentPoint(scrollView).Properties.MouseWheelDelta / -2.5f, 0), null);
}
