If TRUE, users can enter numeric values not already associated with any entries in the list of items defined for a ring control. Users must enter undefined numeric values in the digital display of the control. If FALSE, users must select from the list of items defined for the control.

This property is similar to the [[Allow Undefined Values]] item on the shortcut menu of a ring control and the '''Allow undefined values at run time''' checkbox on the [[Edit Items]] page of the '''Ring Control Properties''' dialog box.
