Is there a way to get the index of an item inside the group?

[jprobert]

For example group 1 got 15 items, how can I get that index? Or how do I know what the first or last item of that group is?

Can you elaborate? Or have you solved this already?

I was able to bypass it by sorting the List before passing it to the GroupedListView. In that way the index will always match the item in the list.
