I'm following this example: http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/treeviewcombobox/defaultcs.aspx
This works great. But what I want is for the RadComboBox drop down not to collapse when clicking on the root element. My tree is two levels deep always, and for the child only do I want the selection to happen. I have this working great, but I need to cancel the drop down collapse, is there something passed in through the event arg for this?
