Objective-C
Java
C++

public void Ungroup()

'Declaration
 
Public Sub Ungroup()

'Usage
 
Dim instance As AnnGroupObject
 
instance.Ungroup()

public:
void Ungroup();

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

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

This example groups/ungroups objects.
