Hi,

You can set any custom object to the Tag property of the shape. The Tag by itself is not used by the diagram, so this gives you the ability to attach any custom information to any diagram element. There are several requirements that custom tag objects must implement:

1. They need to be marked as [Serializable].
2. They need to implement the ICloneable interface.
3. They need to have a default public constructor.

I want to add more property for every shape
So I tried to create a cusom class that inherited from Nshape
but I failed because the Nshape has no new construction and is created by factory
How could I implement this functionality
