Hi, 

I am evaluating latest downloaded Telerik controls. Will be buying them within 1 month or so. My question is for the TreeView data binding.

I am having these fields from SQL database.

STATENAME -> STATECODE
CITYNAME - > CITYCODE
DEVICENAME -> DEVICECODE

Now I want TreeView to bind in such a way that STATENAME becomes parent, CITYNAME becomes Child and DEVICENAME becomes grand Child. Can you please let me know how to do that with properties of the tree control? What if depth goes more?

I also want each CODE to be assigned to each respected field so that when user will select any node using context menu I should get the code of the selected node. 

I am new to Rad controls so please let me know descriptive explanation with code.

Thanks
