Ungroup Method

Summary

Ungroups this AnnGroupObject object.

Syntax

C#
VB
C++
public void Ungroup() 
  
Public Sub Ungroup()  
public: 
void Ungroup();

Remarks

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.

Example

This example groups/ungroups objects.
