The RadListView control changes its scroll position to the Top of the control when expand/collapse groups or toggling the layout
Currently RadListView has only pullTorefresh which updates the list if user scrolling the list downwards.. But it is good to have pullUptorefresh kind of gesture. since mostly we need to populate the list when user scrolling up. a gesture direction setting (pullup or down) would do.
Calling ScrollIntoView method does not affect the scroll position of RadListView when the control is placed inside NavigationPage
