c# - How to scroll to start in a CollectionView with ScrollTo?

Question

I have a CollectionView in which I add new elements by pressing a Button. The new elements are added on top of each other. What I want to do is that every time a new element is added, it scrolls to the last element added above.

scrollTo is in a try clause and every time I put this line it accesses the catch and it doesn't work:

View.CollectionView.ScrollTo(ScrollToPosition.Start);

I tried with ItemsUpdatingScrollMode in xaml with all options but don't scrolls up.

Answer 1

CollectionView.ScrollTo Method has the following overloads

ScrollTo(Int32, Int32, ScrollToPosition, Boolean)   
ScrollTo(Object, Object, ScrollToPosition, Boolean)

So you need to pass the index or model of the item that you want to scrolol to .

For example

View.CollectionView.ScrollTo(0);
