Draging diagram nodes without implementing ICLoneable

I have a diagram which binds to my custom data, by setting the "Tag" attribute of each of the shapes in the diagram.
When I try to move one of the shapes in the diagram, by dragging, I get a message "In order to deeply copiable non primitive types must implement ICLoneable"
Is there a way to prevent this message from showing? I don't want to change my data source to inherit ICloneable etc.

Hi,

ICloneable must be implemented for the type you assign to the Tag property of the shapes.

Hi,

After rereading your post I think that we need to clarify a little. If you are assigning a data source as a Tag value, this does not mean that you need to clone the data source, but rather create a surrogate object that is ICloneable and performs shallow cloning of its members. For example:

[Serializable]
public class MyTag : ICloneable
{
public MyTag()
{
}
public object Clone()
{
MyTag clone = MyTag();
clone.DataSource = DataSource;
return clone;
}
public object DataSource;
}
