Hi dCODE,
In your case it is better to use the RadTreeView SelectedContainer property, instead of the SelectedItem property. After you get the SelectedContainer you can use the NextItem, PreviousItem, ParentItem properties of the RadTreeViewItem to get the next, previous and parent items accordingly. If you need to get all of the children of the currently selected item you can use the ItemsSource property.
RadTreeViewItem selectedContainer = treeView.SelectedContainer;
RadTreeViewItem nextItem = selectedContainer.NextItem;
RadTreeViewItem previousItem = selectedContainer.PreviousItem;
RadTreeViewItem parent = selectedContainer.ParentItem;
IEnumerable childCollection = selectedContainer.ItemsSource;
I prepared an example for you. Please take a look at it and let me know if it helps or if your scenario requires a different approach.
All the best,
