Is there no autobinding for drag\drop using an OpenAccess datasource or am I just missing the property\setting?
If there isn't can this be a PITS issue please :) Way easier like the RadTreeList to drag\drop than having to manually handle OnDrop

Hi Steve,
RadTreeView does not support bi-directional binding.
Since the control has very rich client and server-side API (definitely considering it's a UI element/object/widget etc.), we are very careful on adding more functionality, because even only assessing size of JavaScript rendered to the client, in certain cases it becomes a performance issue. Implementing a bidirectional binding will severely threaten performance, not only in JavaScript rendered, but also in persisted state.
In Drag&Drop and all scenarios involving a change to the TreeView, we provide the events needed for applying changes to your data source.
I hope that you will understand our concerns, and I apologize for any inconvenience caused.
Regards,
