Could you check that group membership is saved in JSON files? When I load my binary Diagram and then save it to a JSON file and then re-load it, group membership of DiagramNodes seems to have been lost.

To create groups, I do this...

        protected Group SubordinateGroup(ShapeNode box)
        {
            // Returns box's subordinate group, creates the group if it does not exist
            var g = box.SubordinateGroup;

            if (g == null)
            {
                // Group not there yet - create a group, using 'box' as the master
                g = FlowChart.Factory.CreateGroup(box);

                g.AutoDeleteItems = true;
                g.Expandable = true;
            }

            return g;
        }

and to attach nodes to a group I do this sort of thing...

                // Attach 'boxLabel' to the group
                SubordinateGroup(box).AttachToCorner(boxLabel, BottomLeft);

When you save and load the JSON file in your example program and then delete a main box, the label box is left behind and not deleted as I expected and observed when saving and loading a binary file.

I assume that this was the loss of group membership. Perhaps there is another reason.

Thank you. That works well.

The only other problem I have now is that boxes in my chart can seem to end up in reverse order when a binary file is saved as a JSON file and then reloaded. It does not happen to all branches in the chart and I can't seem to reproduce it, which is very annoying.

I have attached two pictures.

Yes, we do use the TreeLayout.

This build saves the order of nodes' in/out links in JSON, and should hopefully fix TreeLayout differences -
