Windows Phone 8.1 Grid Row Auto Scroll - xaml

Question

I have created Page where there is grid with three rows. In first row I have two button working as Toggle button. This button will visible or collapsed the content of the second and third row.
In second row I have form bigger than screen and in third row there ListView with Sticky and Grouped Style Header
Now the issue is that as the content in second grid row is more I have kept Page level scroll but when I put page level scroll than it will stop sticky header effect in ListView and when I remove page level scroll then ListView sticky header starts working properly but second row which have form bigger than screen will not scroll. So I was looking something that make my second row auto scroll.
Please somebody help to resolve it.

Answer 1

One simple solution would be to put the just Grid in your second row into a ScrollViewer.
It will work but the user experience would be really, having a page with two separate scrollable parts. I would suggest you split to page into two separate pages, one with the Grid from the second row and another with the ListView from the third row.
