Hello!

Can this be done by creating a "global" list (with fields id_item, id_parent, name) where each datasource will have different prefix for id_item and id_parent fields?

I tryed to create list from only one datasource with mentioned fields and after databinding it to RadTreeView instead of hierarchical tree every node was in 0 level (in List items had correct id_parent value).

EDIT:

I think my question is related to this topic:

Can I databind List with hierarchical data to RadTreeView and keep hierarchy?

Hello GrZeCh,

RadTreeView can databind hierarchically only to DataSet/DataTable/DataView and classes which implement IHierarchicalDataSource/IHierarchicalEnumerable. We have a code library demonstrating how to create a custom IHierarchicalDataSource. You can check it out here.

as far I can see in provided example there is different approach for hierarchy (no ParentID usage)

Is this possible to databind RadTreeView with Dictionary created using methond mentioned in this post (or maybe modified version of this method):

Hi GrZeCh,

No. RadTreeView can only bind to IHierarchicalDataSource/IHierarchicalEnumerable and DataSet/DataTable/DataView. You may consider programmatically creating nodes by traversing your dictionary object.
