Get the Maximum and current value of Scrollbar in Listview
As the title say:
I want to know values of a scrollbar in the ListView such as:
- Minimum value I know = 0 :)
- Maximum value of a scrollbar
- Current value (position of a bar inside of a scrollbar)
Is this possible?
How to make it work for both iOS and Android?
I have tried with ItemAppear to get the position in the ListView but all I can get is the position of an item not the actual scrollbar position and with ItemAppear the problem is if I have big images in the list then I scroll 1 mile but nothing happens until the other item appears.

ListView doesn't fire Scrolled events like ScrollView does.
If you still want to get current value or maximum value of scrollbar, I suggest you can render new Listview, that contains scrolled event. or you can search some third party control, may be have this event.
