Hello,

I have a delegate command that moves a node up or down. I want the item to be active after reordering in order to use the keyboard arrow keys to navigate through the other items. How can i achieve that? I tried to bind the ActiveDataItem property in the XamDataTree with my ActiveItem property in the VM but with no result.

public DelegateCommand<object> MoveUpCommand { get; set; }

MoveUpCommand = new DelegateCommand<object>(OnMoveUp, CanMoveUp);

 public NodeItem ActiveItem { get; set; }

 private void OnMoveUp(object obj)
        {
            var item = obj as NodeItem;
            var index = Nodes.IndexOf(item);
            Nodes.Move(index, index+ 1);
            ActiveItem = item;
        }

        private bool CanMoveUp(object obj)
        {
            var item = obj as ActiveItem;
            return Nodes.IndexOf(item) != 0;          
        }
