[ScrollHeader] GridView does not recall scroll position.

[OneKareithi]

Before adding the Scroll Header to my Grid View, it usually would recall the scroll position when one navigates back to the page. Now I have to do that with code behind which brings an issue where the Grid view is populated with a lot of data and hence the UI kind of flicks before scrolling to the previously selected item.

Hey @kareithi , do you mind providing a repro project for this?

Ok here's a sample app I created. Compiles and runs to demonstrate the issue. Uploaded at https://github.com/Kareithi/Sampleapp01. The app has a pivot with a movies and tv shows page, the movies page has an AdaptiveGridView without a ScrollHeader and recalls scroll positon while the tv shows page has an AdaptiveGridView with a ScrollHeader but doesn't recall scroll position when navigating back.

I was curious if the AdaptiveGridView could have also been contributing to the problem so I tried a regular GridView and the situation was similar so I guess either I'm doing something wrong or there's a bug with the ScrollHeader control.

Thanks @kareithi , I'll take a look later this week

#1234 should fix this issue, thanks for reporting it.

The ScrollHeader was a tabstop which forced the page to scroll to the top since it was the first element. The fix will resolve this. However, in your code, you had a AutoSuggestBox inside the ScrollHeader which in itself is a tabstop, and will create the same behavior (even if not using the ScrollHeader)
