Hi David Cardona,
You could provide a runnable sample and we will try to investigate your issue in depth. Is your tree bound to a collection of objects ? Can you make sure that you are trying to work with a RadTreeViewItem that is already generated ( usually it happens when it is loaded in the tree root level collection or one of its parent item has been expanded so that the needed item becomes visible. You can find more info on this topic here
. Thank you for your cooperation in advance.
All the best,
the Telerik team
