Remarks
The example below shows how to group two OLE objects. Use the ShapeCollection.InsertGroup method to create a shape group. The Shape.GroupItems property returns a collection of group elements. Call the AddOleObject methods to add OLE objects to the group.
Document document = wordProcessor.Document;
// Set measurement unit to inches.
document.Unit = DevExpress.Office.DocumentUnit.Inch;
// Insert a shape group.
Shape group = document.Shapes.InsertGroup(document.Range.Start);
// Access the collection of group items.
var groupItems = group.GroupItems;
// Add the first OLE object to the group.
// This object contains data from an Excel worksheet.
using (Stream excelStream = File.Open(@"D:\ExcelWorkbook.xlsx", FileMode.Open))
{
groupItems.AddOleObject(excelStream, OleObjectType.ExcelWorksheet,
System.Drawing.Image.FromFile(@"Images\Spreadsheet.png"), new PointF(0f, 0f));
}
// Add the second OLE object to the group.
// The object links to an Excel chart sheet.
groupItems.AddOleObject(@"D:\ExcelChart.xlsx", OleObjectType.ExcelChart,
System.Drawing.Image.FromFile(@"Images\ExcelChart.png"), new RectangleF(0.5f, 1.2f, 5f, 3.5f));
