Ungroup Method (AnnGroupObject)

Example 





Leadtools.Windows.Annotations Namespace > AnnGroupObject Class : Ungroup Method
Ungroups this AnnGroupObject object. .NET support Silverlight support
Syntax
public void Ungroup()
'Declaration
 
Public Sub Ungroup() 
'Usage
 
Dim instance As AnnGroupObject
 
instance.Ungroup()
public void Ungroup()
 function Leadtools.Windows.Annotations.AnnGroupObject.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.
