How to hook in the copy and paste methods?

Hi Walter,
yes I can override CommandHandler Methods - but I don’t know how!
Must I write a new CustomCommandHandler and inherit CommandHandler? Which of the classes (Diagram, Manager…) has the CommandHandler?

I just don’t know how?

I’ve tried:

public class CustomCommandHandler : CommandHandler
{
    public override void Copy()
    {
        base.Copy();
    }

    public override void Paste()
    {
        base.Paste();
    }
}

and then on another place:

MyDiagram.CommandHandler = new CustomCommandHandler();

Is this the right way?

Can I get the parts to paste in the Paste-Method and do some additional operation with them?

One of my issues is that my Node.Data has a Brush-Property. This Brush-Property is not serializable. If I know the Parts to copy and the Parts to paste then I can copy the Brush-Property by my own.

Also, just for information, if the Data is not serializable there is a message in the output window:
Error in model
CopyNode1: over this method to copy nodes, or have…

where is this CopyNode1 methode?
