Since the drag and drop functionality will not fit your scenario, you could try using the Cell Swipe gesture
to move the items in different groups. In the ItemSwipeContentTemplate
you can use buttons that will change the grouping property of the underlying business item. When this is done you will be able to refresh the group descriptor of the RadListView in order to update the UI and visually move the respective item in the new group.
For your convenience we prepared a simple project demonstrating this approach. Please take a look at it and let us know if it fits your scenario.
