The desired access method is now no longer configurable inside the user control. However, it is available for configuration through the assignment of the virtual permissions as an additional access method of the user control host when using the user control in the designer.

	For the purpose of reusability of the user control, direct configuration of the access methods inside a user control should be dispensed with. The independence of project-specific user groups is achieved with this approach. Accordingly, the default access methods "Observe" and "Operate" should be configured either with "Inherit" or as special access methods via the use of virtual permissions. Special access methods of controls within a user control should always be fed to the outside via the use of virtual permissions because the user control host only has the default access methods "Observe" and "Operate" as standard.
