When you add keybord navigation to the TreeList, alongside with the ability to drag and drop TreeList rows, keyboard events won't fire. http://jsfiddle.net/ahz94f1j/2/ It looks more like an simple oversight, but we asked suppport and they responded that we should make a suggestion here.
Hi,
A TreeList with keyboard navigation and drog and dropping is demonstrated in the following Dojo: https://dojo.telerik.com/OMUkoHEj
