Hello Ali,

Thank you for writing.

I have prepared a sample project demonstrating how to bind RadTreeView to 3-level hierarchical data. When clicking the button its depth is changed to 4. You can follow approach to bind hierarchy. It is just necessary to construct correctly the DisplayMember and ValueMember properties. Additionally, in order to allow add, update, remove operation, you should set the following properties to true:
this.radTreeView1.AllowAdd = true;
this.radTreeView1.AllowEdit = true;
this.radTreeView1.AllowRemove = true;
this.radTreeView1.AllowDefaultContextMenu = true;

I hope this information helps. Should you have further questions, I would be glad to help.
 
Regards,
Dess
