Thank you for the response. However, this does not solve my particular need. Let me explain a little more.
On both Android and iOS, it is perfectly acceptable to have a RadListView within a ScrollView. If you set the height of the RadListView to the exact height of the content, even older versions of Android (like API 19) handle it beautifully. The whole page scrolls exactly like you would expect, and you can have more than just the RadListView on the page.
If I knew the exact height of each row, I could simply set the height of the RadListView equal to the number or rows times the row height. However, I have rows that are different heights due to the content in each row.
So, I am looking for a way to set the RadListView's height to the exact height of all the rows, knowing that each row will have a different height. Simply wrapping it in a Grid, even with setting the VerticalOptions as you suggested, does not accomplish that.
Any other input would be greatly appreciated.
