Ctrl-C For Custom Nodes

Just to revive a question that was raised in this link: http://mindfusion.eu/Forum/YaBB.pl?board=wpfdg_disc;action=display;num=123850285...:

Stoyan Said:   Copy to clipboard won't work if you are using a custom node type that does not override the Clone method nor implements a copy constructor. The control automatically binds the ApplicationCommands.Copy command to the Diagram.CopyToClipboard() method. You could replace it with your own binding if you want to stop Ctrl+C.

I said: Can you say more? What would be the steps/code to replace the binding? What does a Copy constructor look like?

Replacing the binding looks like this:

Code
Select All
diagram.CommandBindings.Add(
	new CommandBinding(ApplicationCommands.Copy, (sender, args) => { }));


A copy constructor is a constructor that takes as an argument an instance of the same type:
Code
Select All
public MyNode(MyNode prototype) : base(prototype)
{
	MyProperty = prototype.MyProperty;
}


I hope that helps,
Stoyan
