The Diagram control provides a set of properties that allow you to restrict end-users from performing certain operations with diagram items.

You can modify the properties of existing diagram items by accessing them using the DiagramControl.Items collection. Alternatively, use the DiagramControl.ItemCreating event to modify the properties of an item that is about to be created.
