The Children property is a zero-based, indexed collection used to hold all the AnnObject objects assigned to this AnnGroupObject. Since the property is read-only, it cannot be assigned a collection of objects directly. Objects can be added or removed by using the methods inherited from the AnnObjectCollection class.
For more information about grouping and ungrouping, refer to Grouping and Ungrouping Annotation Objects.
