Remarks

Ungrouping an AnnGroupObject object moves all the objects in this group to the group's Container. After ungrouping is done, the group's Objects collection will be empty. This method does not remove this AnnGroupObject object from the Container.

For more information about grouping and ungrouping, refer to Grouping and Ungrouping Annotation Objects.
