I am not sure I understand the structure of your entity model and this is why I don't think I understand your scenario. Is your data in a flat collection, is it self-referencing? Or is it a hierarchical data? If it is a hierarchical data can you give us more details about its structure and the way you need to group it?
Basically the RadTreeView
doesn't expose any grouping functionality - it allows you to structure your data in a hierarchy and use HierarchicalDataTemplates
to display it inside the RadTreeViewItems
. All data operations like grouping or sorting, should be applied on the business collection used as the ItemsSource
of the control. You can examine this tutorial
on how to bind the RadTreeView
to a collection of items generated through a WCF service and/or at this forum post
describing how to bind to a flat collection of self-referencing data.
