I'm using the evaluation version and upon deserialization of a diagram with custom nodes, nothing is displayed.

I have created my own node class derived from ShapeNode. I have overriden Loadfromxml and SaveToXml and I have registered the new node type. In fact if i replace my open/save code with calls to LoadFromXml() and SaveToXml() everything works fine.

However, if i replace those calls with LoadFromString() and SaveToString() nothing is displayed. The LoadFromXml() method in my node class is called. After the LoadFromString() is called, the node collection in the diagram does contain my nodes.

I should also point out i have provided my own bitmap image from the node. It is converted to base64string during the node's savetoxml and converted from a base64string duringthe node's loadfromxml.



Any thoughts?

Thanks,
John

Stoyan thanks,

I enabled the 'break when thrown' for CLR exceptions but none were thrown.


FYI: I am using VS 2010 release candidate. I haven't seen any problems with your control.


Thanks again,
John

Stoyan,

I found MY problem. I must be losing my mind! I created a new diagram but didn't set it as the view's diagram.

Thanks so much for the prompt response,

John
