When I put a ListPicker into a ScrollViewer and then try to scroll, if I start the scrolling gesture on the ListPicker, it will open up the ListPicker when I'm done (even though I'm only trying to scroll).
This problem is caused by the fact that the ListPickerMode is changed when the ManipulationComplete event fires, regardless of what kind of manipulation was completed. I solved the problem with the following line of code at 606 of the ListPicker.cs
if ((Math.Abs(e.TotalManipulation.Translation.X) < 20) && (Math.Abs(e.TotalManipulation.Translation.Y) < 20))
{
[Change ListPickerMode]
}
This weeds out any interactions that are more "swipe-y" and less "tap-y". (We could probably actually even reduce the manipulation delta to something like 10 if we wanted to be conservative about it.)
