    I would like to validate drag/drop as the user moves a node over other tree nodes.
    I have the following source:

            $("#treeView").kendoTreeView({
                dragAndDrop: true,
                .......
            }).bind("drag", function(e) {
                var node = $(e.dropTarget).closest(".k-item");

                // Only care if we are dragging to a treeviewitem
                if (!(node.length && node.parents(".k-treeview").length)) return;

                var targetId = $(node).find('.data-id').val();
                if(targetId != 'Testing")
                     // TODO: Mark dragging as invalid?
            });

    But i'm not show how to mark the drag as invalid? Am I going about this the correct way?
