If RadTreeView.IsEnabled false (or the tree is inside busy BusyIndicator), then ExpandItemByPath(or GetItemByPath) does not work. Available in LIB version: 2016.2.525
This is not just a problem with the tree is disabled. ExpandItemByPath and GetItemByPath do not work for virtualized trees using VirtualQueryableCollectionView as an ItemSource.
would you be able to give me a loose time frame one when this will be fixed?
