How can I jam a header onto an Excel sheet I poop out from DevExpress grid data in an MVC app?

This way of doing things needs love if we are going to have a header. In fact, the approach radically changes. I have had an example working, but it yet needs spruce up. The code I offer below is really dirty code but I've been sitting on this for a few days I and I wanted to share it instead of maybe getting to it later. Most of it is stolen from elsewhere, but I don't recall where.

using System.Drawing;
using System.IO;
using System.Linq;
using System.Web.Mvc;
using DevExpress.Web.Mvc;
using DevExpress.XtraPrinting;
using DevExpress.XtraPrintingLinks;
using Modernity.Models;
namespace Modernity.Controllers
{
   public class ExportingController : Controller
   {
      private System.Drawing.Image headerImage;
      
      public ActionResult Export()
      {
         var gridViewSettings = new GridViewSettings();
         gridViewSettings.Name = "whatever";
         gridViewSettings.KeyFieldName = "CustomerID";
         gridViewSettings.Columns.Add("ContactName");
         gridViewSettings.Columns.Add("CompanyName");
         gridViewSettings.Columns.Add("ContactTitle");
         gridViewSettings.Columns.Add("City");
         gridViewSettings.Columns.Add("Phone");
         var printable = GridViewExtension.CreatePrintableObject(gridViewSettings,
               NorthwindDataProvider.GetCustomers());
         
         PrintingSystem ps = new PrintingSystem();
         
         using (this.headerImage = Image.FromFile(Server.MapPath("~\\Content\\pic.png")))
         {
            Link header = new Link();
            header.CreateDetailArea += new
                  CreateAreaEventHandler(header_CreateDetailArea);
            
            PrintableComponentLink link1 = new PrintableComponentLink(ps);
            link1.Component = printable;
            
            CompositeLink compositeLink = new CompositeLink(ps);
            compositeLink.Links.AddRange(new object[] { header, link1 });
            
            compositeLink.CreateDocument();
            using (MemoryStream stream = new MemoryStream())
            {
               compositeLink.PrintingSystem.ExportToXls(stream);
               WriteToResponse("filename", true, "xls", stream);
            }
            ps.Dispose();
         }
         return PartialView("View");
      }
      
      void WriteToResponse(string fileName, bool saveAsFile, string fileFormat,
            MemoryStream stream)
      {
         string disposition = saveAsFile ? "attachment" : "inline";
         Response.Clear();
         Response.Buffer = false;
         Response.AppendHeader("Content-Type", string.Format("application/{0}",
               fileFormat));
         Response.AppendHeader("Content-Transfer-Encoding", "binary");
         Response.AppendHeader("Content-Disposition", string.Format("{0}; filename={1}.
               {2}", disposition, fileName, fileFormat));
         Response.BinaryWrite(stream.GetBuffer());
         Response.End();
      }
      
      void header_CreateDetailArea(object sender, CreateAreaEventArgs e)
      {
         e.Graph.BorderWidth = 0;
      
         Rectangle r = new Rectangle(0, 0, headerImage.Width, headerImage.Height);
         e.Graph.DrawImage(headerImage, r);
      
         r = new Rectangle(0, headerImage.Height, 400, 50);
         e.Graph.DrawString("Additional Header information here....", r);
      }
   }
}
