I've just figured out the Related Comboboxes demo (http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx ) is not using requestItems anymore, It uses a RadAjaxManager.
I'm just curious about it, Have you found some issues? Is this "new" approach faster now?
