Remarks

Create a Shape Group

Call the ShapeCollection.InsertGroup method to create a shape group. The Shape.GroupItems property returns the collection of group items. Use the collection’s Add methods to add drawing objects to the group.

The example below creates a shape group in the document.

C#

Document document = wordProcessor.Document;
// Set the measurement unit to inches.
document.Unit = DevExpress.Office.DocumentUnit.Inch;
// Insert a shape group.
Shape group = document.Shapes.InsertGroup(document.Range.Start);
// Specify the group position relative to the left and top edges of the page. 
group.Offset = new PointF(1.5f, 1f);
// Access the collection of group items. 
var groupItems = group.GroupItems;
// Add a rectangle to the group.
var shape1 = groupItems.AddShape(ShapeGeometryPreset.Rectangle, new RectangleF(0f, 0f, 2f, 1.5f));
shape1.Fill.SetSolidFill(Color.FromArgb(0xA4, 0xFF, 0xFF));
shape1.Line.Color = Color.DarkGray;
shape1.Line.Thickness = 2;
// Add a picture to the group.
var shape2 = groupItems.AddPicture(DocumentImageSource.FromFile("Picture_Arrow.png"), new PointF(2.1f, 0.3f));
// Add a parallelogram to the group.
var shape3 = groupItems.AddShape(ShapeGeometryPreset.Parallelogram, new RectangleF(3.8f, 0f, 2f, 1.5f));
shape3.Fill.SetSolidFill(Color.FromArgb(0xFF, 0xA5, 0xA5));
shape3.Line.Color = Color.DarkGray;
shape3.Line.Thickness = 2;

VB.NET

Dim document As Document = wordProcessor.Document
' Set the measurement unit to inches.
document.Unit = DevExpress.Office.DocumentUnit.Inch
' Insert a shape group.
Dim group As Shape = document.Shapes.InsertGroup(document.Range.Start)
' Specify the group position relative to the left and top edges of the page. 
group.Offset = New PointF(1.5F, 1F)
' Access the collection of group items. 
Dim groupItems As GroupShapeCollection = group.GroupItems
' Add a rectangle to the group.
Dim shape1 As NestedShape = groupItems.AddShape(ShapeGeometryPreset.Rectangle, New RectangleF(0F, 0F, 2F, 1.5F))
shape1.Fill.SetSolidFill(Color.FromArgb(&HA4, &HFF, &HFF))
shape1.Line.Color = Color.DarkGray
shape1.Line.Thickness = 2
' Add a picture to the group.
Dim shape2 As NestedShape = groupItems.AddPicture(DocumentImageSource.FromFile("Picture_Arrow.png"), New PointF(2.1F, 0.3F))
' Add a parallelogram to the group.
Dim shape3 As NestedShape = groupItems.AddShape(ShapeGeometryPreset.Parallelogram, New RectangleF(3.8F, 0F, 2F, 1.5F))
shape3.Fill.SetSolidFill(Color.FromArgb(&HFF, &HA5, &HA5))
shape3.Line.Color = Color.DarkGray
shape3.Line.Thickness = 2

Ungroup Shapes

Use the GroupShapeCollection.Ungroup method to split a group into individual shapes.

The example below shows how to split all shape groups in the document (including nested groups):

C#

using System.Linq;
// ...

Document document = wordProcessor.Document;
List<DrawingObject> groups = document.Shapes.Flatten()
    .Where(x => x.Type == ShapeType.Group)
    .ToList();
for (int i = groups.Count - 1; i >= 0; i--)
{
    groups[i].GroupItems.Ungroup();
}

VB.NET

Imports System.Linq
' ...

Private document As Document = wordProcessor.Document
Private groups As List(Of DrawingObject) = document.Shapes.Flatten() _
        .Where(Function(x) x.Type = ShapeType.Group) _
        .ToList()
For i As Integer = groups.Count - 1 To 0 Step -1
    groups(i).GroupItems.Ungroup()
Next i
