TREE LIKE STRUCTURE / GRID IN LISTVIEW XAF BUSINESS OBJECT : I have been having super difficulties on creating a view that will display my data grouped in levels (Screenshot attached).

I don't know on how to go about this, my data is stored in **ONE single table** in database which is mapped to a business object in application. Therefore what I want is to **group elements based on PROPERTIES** (attributes of table) , for instance, group level one based on first property etc. 

Probably some of you may have worked previously on devexpress and have some suggestions. 

It would be extremely helpful if you could help on this.


Thank you !!!
