public class AnnGroupObject : AnnRectangleObject, IAnnGroup, IAnnHeader, IAnnObject, IAnnRectangle

'Declaration
 
Public Class AnnGroupObject 
   Inherits AnnRectangleObject
   Implements IAnnGroup, IAnnHeader, IAnnObject, IAnnRectangle

'Usage
 
Dim instance As AnnGroupObject

public ref class AnnGroupObject : public AnnRectangleObject, IAnnGroup, IAnnHeader, IAnnObject, IAnnRectangle

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.

This example moves all the objects from a container into a new group object.
