object that represents the common parent shape of a child shape or a range of child shapes.
expression.ParentGroupShape
expression Required. An expression that returns one of the objects in the Applies To list.
Example
This example creates two shapes in the active document and groups those shapes. Then using one shape in the group, it accesses the parent group and fills all shapes in the parent group with the same fill pattern. This example assumes that the active document does not currently contain any shapes. If it does, an error may occur.
Sub ParentGroupShape()
Dim shpGroup As Shape
With ActiveDocument.Pages(1).Shapes
.AddShape Type:=msoShapeOval, Left:=72, _
Top:=72, Width:=100, Height:=100
.AddShape Type:=msoShapeHeart, Left:=110, _
Top:=120, Width:=100, Height:=100
.Range(Array(1, 2)).Group
End With
Set shpGroup = ActiveDocument.Pages(1).Shapes(1) _
.GroupItems(1).ParentGroupShape
shpGroup.Fill.Patterned Pattern:=msoPattern25Percent
End Sub
