	Hi Can you please provide sample source code which demonstrate how to serialize/deserialize a diagram with a my own CustomShapeNode class which is inherited from 'ShapeNode'. Also I want to show a context menu when i right click on my 'CustomShapeNode' class. What's the easiest way to achieve this? I see ShapeNode class has a 'ContextMenu' property. thanks, Shiju

	Hi, You can find serialization of derived node types demonstrated in Tutorial 4. In short, call RegisterItemClass method to map your class to a string id used in XML files, and override the SaveToXml and LoadFromXml methods of the base node type to serialize your additional properties. To show a context menu, handle the NodeClicked event and set ContextMenu.IsOpen from inside an if block: Code if (e.Button == MouseButton.Right && e.Node is CustomShapeNode) ... Check the TreeLayout example for a sample event handler. I hope that helps, Stoyan
