Hello Hugo,
Since none of our RadControls fit to the scenario out of the box, I spent some time playing with several controls and I came up with a solution (attached) that I think is very close to what you need.
I have developed a custom user control (
VistaExplorerBar) that can be used on a form to resemble the vista explorer panel bar look and feel. The API may need some further polishing but you should be able to get the basic idea by this demo. The user control is built using
RadlistBox, RadDropDownButton, RadTreeView, RadPanel, SplitContainer and some custom themes for the corresponding controls.
Please let me know if this works for you.
All the best,
Mike
