Two new ControlExamples on the ListView samples page, based on the UWP XamlListView reference sample: - ScrollIntoView: NumberBox + alignment ComboBox drive ListView.ScrollIntoView with ScrollIntoViewAlignment.Default or Leading. - Save/restore scroll position: demonstrates ListViewPersistenceHelper.GetRelativeScrollPosition and SetRelativeScrollPositionAsync, the same API a real app would use to restore position after navigating away and back.

- Items are prefixed with their 1-based index (e.g. '1. John Doe') so it is easy to verify save/restore and ScrollIntoView landed on the expected entry. - NumberBox now sets Maximum, SmallChange/LargeChange, and ValidationMode so manually typed indices are preserved instead of reverting.

There was a problem hiding this comment.
Besides the showing of the raw position blob, LGTM!
