'vb.net Dotnetbar AdvTree - How to expand Node while hovering? Not delete original items?

I'm using vb.net and the AdvTree Treeview from DotNetBar. I'm dropping items from one AdvTree to another. The 'source' tree is really in more of a ListView format. The 'destination' tree in a typical tree format, like this:

Project List Boxes

When I drag from the right side over to the left I need the drag to be able to 'select' the nodes. For example, the highlighted cell AKP_Sine4 I should only be able to drag into either AllData or Top5 groups. However, unless I expand those groups to drag it underneath - it will have the top level pre-selected.

I assume I need to use the DragOver event, but I haven't figured out how to make it expand and/or select those nodes when I dragover them :(

Thanks in advance.
