BUG. RadTreeView throws an exception when an object is being added and delete from its undelying BindingSource

RadTreeView does not refresh iteself after adding a node on a second level.

The background changes to white when clicking an item in RadTreeView and using Office 2010 theme.

There is a single pixel behind the vertical scrollbar in RadTreeView where the text of long tree nodes is visible.

The built-in drag-and-drop mechanism in RadTreeView should be revisited. Currently some events are not raised properly under certain conditions.

When self reference data binding is in place, editing a root node throws a null reference exception.

Nodes are not always dropped successfully on another treeview when the source nodes are selected.

Some nodes do not auto-expand when hovered while dragging nodes.

DragEnding event is not fired in some cases.

Sometimes, e.Node and e.TargetNode are null in the DragEnded event handler
