//Add a page to the document.
PdfPage page = document.Pages.Add();

//Create PDF graphics for the page.
PdfGraphics graphics = page.Graphics;
//Load the image from the disk.
var assembly = Assembly.GetExecutingAssembly();
var imageStream = assembly.GetManifestResourceStream("Create-PDF-document.Data.AdventureCycle.jpg");
PdfBitmap image = new PdfBitmap(imageStream);
//Draw an image.
graphics.DrawImage(image, new RectangleF(130, 0, 250, 100));

//Draw header text. 
graphics.DrawString("Adventure Works Cycles", new PdfStandardFont(PdfFontFamily.TimesRoman, 20, PdfFontStyle.Bold), PdfBrushes.Gray, new PointF(150, 150));

PdfTextElement textElement = new PdfTextElement(text, new PdfStandardFont(PdfFontFamily.TimesRoman, 12));
//Draw the text in the first column.
textElement.Draw(page, new RectangleF(0, 200, page.GetClientSize().Width, page.GetClientSize().Height));

//Create a PdfGrid.
PdfGrid pdfGrid = new PdfGrid();
//Add values to the list.
List<object> data = new List<object>();
Object row1 = new { Product_ID = "1001", Product_Name = "Bicycle", Price = "10,000" };
Object row2 = new { Product_ID = "1002", Product_Name = "Head Light", Price = "3,000" };
Object row3 = new { Product_ID = "1003", Product_Name = "Break wire", Price = "1,500" };
data.Add(row1);
data.Add(row2);
data.Add(row3);
//Add list to IEnumerable.
IEnumerable<object> dataTable = data;
//Assign data source.
pdfGrid.DataSource = dataTable;
//Apply built-in table style.
pdfGrid.ApplyBuiltinStyle(PdfGridBuiltinStyle.GridTable4Accent3);
//Draw the grid to the page of PDF document.
pdfGrid.Draw(graphics, new RectangleF(0, 300, page.Size.Width - 80, 0));

//Save and close the PDF document  
MemoryStream ms = new MemoryStream();
document.Save(ms);
document.Close();
ms.Position = 0;

HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK);
response.Content = new ByteArrayContent(ms.ToArray());
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
    FileName = "Sample.pdf"
};
response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/pdf");
return response;
