1) The prometheus help doesn't list the TreeView anywhere so it's kinda difficult to find help. This isn't good because the control is in the official suite and not a futures release.
2) I can't get the context menu to work with a databound treeview. In fact, attempting to use a context menu with a databound treeview causes the expand / collapse of nodes to no longer function.
There are still a few site updates pending for the Q3 release, including the TreeView forums. Expect those to be complete tomorrow (Wednesday). In the mean time, thanks for the feedback. I'll make sure our devs respond to the question about the context menus and databinding ASAP.
