In case you lower down the number of items, the RadListView control would not lower its height in situations where you expect this to happen.

The grouping does not work in Android if you do not use simple type properties to group the items. In UWP everything works fine, in iOS I have not tested the scenario. I added a demo solution to test the issue.
