title: vb.net Dotnetbar AdvTree - How to expand Node while hovering? Not delete original items?
body: <p>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:</p>
  <p><a href="https://i.stack.imgur.com/LRKFE.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/LRKFE.png" alt="Project List Boxes" /></a></p>
  <p>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.</p>
  <p>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 :(</p>
  <p>Thanks in advance.</p>
