A TreeView in ComboBox - once again

A TreeView in ComboBox would be most helpful as both a stand-alone control and when editing within the Grid.

something like this: http://www.brad-smith.info/blog/archives/193 (example from .NET Windows forms world)

* Used for relative small tree data structure.
* User may select one (many) item(s), without _loosing context_ (no interrupting dialog box, 'flat' interface).
* User may accept selection by click on item, or pressing 'enter'.
* User may cancel (hide) popup when click outside control/popup (ie in another control, that received focus) or pressing escape - like in combobox/dropdown.
* It will be nice if user can select items using keyboard arrows.
* After opening popup or selecting item, widget still has focus
* When user types in combo (with open popup), data should be filtered.
* No additional 'ok' or 'cancel' buttons to accept/dismiss selection.

        I'm using Telerik Controls on the WPF and ASP.NET side since many years. I use some KendoUI controls for Special Features for around 3 years and I would like to see more robust business features in KendoUI in the future! For me a good grid/TreeList and a good Combobox/AutoComplete/MultiSelect with list, grid and tree selection - a high performing "All in one Select Control" :-) is very important. KendoUI could close this gap on the HTML5 widget market....
