    The app I am working has child windows (RadWindow).  Both parent and child window have drag and drop operations.  I am still trying to understand the RadDragAndDropManager and how it operates.  What is the best way for me to do selective drag and drop?  For example, if the child window is up, I wouldn’t want the drop target in the parent window to get the dragged items.  Also, what do I need to do if I want prevent some type of nodes on the RadTreeView to be not draggable?  

    Also, I noticed that in the RadTreeView there are a quite a lot of properties related to drag and drop.  For example:  IsDragDropEnabled, AllowDrop.  Depends on the value that is set on these properties, some of the event is not fired.  I wonder where the documentation is for these properties.  I think IsDragDropEnabled is for within the RadTreeView drag and drop but I am not 100% sure.  If IsDragDropEnabled is set to false, the DragQuery Event is not fired.  Can someone clarify this?  Thanks.
