Hi Chris,

You will have to implement the custom node class on the server side too, and call RegisterItemClass to be able to load the diagram XML.

You will also have to implement the node.Draw method using GDI+ code, or from what I have seen in your screenshots you might easily replace the custom nodes with TableNodes to reuse their rendering. E.g. the table would have 2 columns x 8 rows, and you can copy the custom data to the table cells and set ColumnSpan = 2 for the image cell.

Implementing node.Draw won't be much more work than transferring the custom data to a TableNode though.

I hope that helps,
Stoyan
