Hi,
In Servoy 3.5.1, DBTreeView Bean is improvised a lot in the areas of automatic refreshing, node selection as well in the node status(Expanded/Collapsed), It would be again better if it will support drag & drop functionality as well.
That mean, user can drag a node and drop to any one(node), accordingly, new records or existing records can be created and deleted in the table in which the DBTreeView is based upon along with triggering a servoy method, so that it can be customizable as well.
