As far as I understood, HierarchicalDataSource does not have get method, meaning recursively traverse the structure for a node by its attribute. Am I correct?

That is a great question - I have spent countless hours trying to figure this out.

According to this post (http://www.kendoui.com/forums/ui/treeview/programatically-select-a-tree-node.aspx#2307355) get() is supposed to work on hierarchical datasources.

But all my testing has shown me that get() only works on the top level children - it does not recursively work.  I hope Kendo works on the documentation on this area.

I have opened support tickets to see if I have missed something but no response so far.

Hi Sergey,

Please note that from the KendoUI 2012 Q3 release the Get method searches through all currently loaded nodes. If you need to search through all nodes you should set the LoadOnDemand option to false.
