item.Constraints = NodeConstraints.Select | NodeConstraints.AllowDrop | (NodeConstraints.Drag) ;
when I did this I can still be able to perform all default constraints like add/delete etc.My main requirement is to avoid delete and add functionalities.i was able to use
&~(NodeConstraints.Delete).But i didnot find constraint for add(copy/paste-cntrl+c/v).Is there any other way to avoid add/delete functionality
