Remarks
The annotation group object contains a collection of annotation objects from any class that is derived from theAnnObject class. This collection of objects can be treated as one while they are in a group. An annotation object can be in either a container or a group but not both at the same time.
For more information about grouping and ungrouping, refer to Grouping and Ungrouping WPF Annotation Objects.
