Treeview - Maintain selected state using Master Page & SQL Datasource

[Kourtney]

I'm using a SQL Datasource for my treeview in a master page.  I would like to know how to maintain the selected state after postback?  Is it possible to define this by the datsource primary key (TreeView - DataFieldID) of the selected item?

Did you ever get a response? I have the same issue and the sample code does not work with a SQL Datasource.
