	I created a new diagram,and load xml into this diagram. Then I add items from new diagram into my mainDiagram one by one. But if new diagram has group, and node in mainDiagram, the MasterGroup will be gone(null). It will be ungroup. So how can I do ???????? Please tall me~~

	If you are calling node's copy constructor and adding the copy to main diagram, that won't automatically copy group object and child nodes. You could copy the child nodes separately in a loop and attach them again to master copy. If doing that on server side, you could select all items from the group and call CopySelection and PasteSelection methods with copyGroups argument set to true.

	Do you mean copying your own properties for custom item classes? Diagram.CopySelection calls items' Clone method, and default Clone implementation calls copy constructor of the class. So for custom properties support you must either add a copy constructor or override Clone method in the derived class. Regards, Slavcho
