I am using RadTreeListView with (LazyLoading), to populate the hierarchical items in tree structure. I have a requirement to bring the selected item to top of RadTreeListVIew. I had tried ScrollToVerticalOffset/ScrollIndexIntoView/ScrollIntoViewAsync but these APIs does not help my requirement. All these APIs just bring the item to the view but not to the top of the TreeList. Please let us know how to achieve the same.
The tree has almost 20000 items in hierarchical manner.
Thanks in Advance,
