we're trying to use drag and drop on a listbox and 2 tree views.
the premise is that listbox can drop into TreeView A but cannot drop into TreeViewB
TreeViewA has a 2 level hierarchy
TreeView A can drop the parent (1st level nodes) node (using say CustomerViewModel) into TreeViewB only
TreeView A can drop the child nodes (say for example ProductViewModel) back into the listbox only
TreeViewB also has a 2 level hierarchy
TreeViewB cannot drop its parent node (1st level nodes which is of GroupViewModel) anywhere
TreeView can drop its child nodes (which is CustomerViewModel) back into TreeViewA
we tried adding a handler into the TreeView, but only AddDropInfoHandler is working. AddDropQueryHandler doesn't pass into the defined handler...
