Undo ClearAll

--- For example:---

Diagram diagram = new Diagram()...
... stuff added to diagram by user ...

... user decides to clear all items in diagram so program calls
diagram.ClearAll();

... now user changes their mind and wants to undo clear all -
diagram.UndoManager.Undo();

------

So the call to Undo from UndoManager does not bring back the diagram before ClearAll was called...
I'm not sure if we already have this in place, but I don't see an easy way to undo the clear all function. Any suggestions?

Thanks!

ClearAll also clears the undo manager history, so it's not possible to undo it. Instead of ClearAll, you could call Diagram.StartComposite and delete all items.

I hope that helps,
Stoyan
