I've been trying to use Forms Picker and it looks like it has different behavior on Android/Windows Phone and on iOS.
https://developer.xamarin.com/api/type/Xamarin.Forms.Picker/
On iOS event SelectedIndexChanged is fired as soon when picker stops scrolling on one of the items.
On other systems, event is fired when user accepts the choice and exits the picker.
This is problematic, because I'd like to make decision based on what user selects, not what picker is showing during selection.
I know no way to get event when user actually touches "Done" on screen.
Forms 1.5
I cannot use 2.0 because of current catastrophic Windows Phone problems.
