I actually checked the showcase example (again) and found the way you implemented the Sidebar Nav Tree !

I now made a small test - and if i also make it like that (to create a TreeNode instance) for all my records i can show the different levels of each object !

The only question open then would be:

How can i force a refresh witin runtime for this TreeGrid - if there is no "DataSource" attached (only a TreeNode[]) ??

To completely replace the dataset for a non-databound TreeGrid just call setData() with a new Tree. For incremental changes just modify the Tree via it's APIs and the TreeGrid will automatically react and show changes.
