Suppose we have a RadTreeView consisting of Teams and Players hierarchy. If you move a player from one team to another, you can update your parent or parentId like so:
sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
(e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add)
Player movedPlayer = (sender
The CollectionChanged event of the Players collection will fire with every drag and drop operation that moves a player from one team to another.
Please let us know if this approach satisfies you.
All the best,
the Telerik team
