Create PDF from DataTable in Asp.net

In this article ,i am explaining you how to create pdf file from datatable.i am passing a datatable in this function and code to convert this in pdf file.

I am using iTextSharp you can download it from internet. it is free.
you need to create a simple asp.net page and get data from database.Then pass it to ExportToPDF method.We can set PDF page margins, change page orientation (portrait, landscape), customize headers and footers add page numbers and more.Do some R & D with iTextSharp.


 public void ExportToPdf(DataTable myDataTable)  
{
Document pdfDoc = new Document(PageSize.A4, 10, 10, 10, 10);
try
{
PdfWriter.GetInstance(pdfDoc, System.Web.HttpContext.Current.Response.OutputStream);
pdfDoc.Open();
Chunk c = new Chunk("" + System.Web.HttpContext.Current.Session["CompanyName"] + "", FontFactory.GetFont("Verdana", 11));
Paragraph p = new Paragraph();
p.Alignment = Element.ALIGN_CENTER;
p.Add(c);
pdfDoc.Add(p);
string clientLogo = System.Web.HttpContext.Current.Session["CompanyName"].ToString();
clientLogo = clientLogo.Replace(" ", "");
string clogo = clientLogo + ".jpg";
string imageFilePath = System.Web.HttpContext.Current.Server.MapPath("../ClientLogo/" + clogo + "");
iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageFilePath);
//Resize image depend upon your need
jpg.ScaleToFit(80f, 60f);
//Give space before image
jpg.SpacingBefore = 0f;
//Give some space after the image
jpg.SpacingAfter = 1f;
jpg.Alignment = Element.HEADER;
pdfDoc.Add(jpg);
Font font8 = FontFactory.GetFont("ARIAL", 7);
DataTable dt = myDataTable;
if (dt != null)
{
//Craete instance of the pdf table and set the number of column in that table
PdfPTable PdfTable = new PdfPTable(dt.Columns.Count);
PdfPCell PdfPCell = null;
for (int rows = 0; rows < dt.Rows.Count; rows++)
{
for (int column = 0; column < dt.Columns.Count; column++)
{
PdfPCell = new PdfPCell(new Phrase(new Chunk(dt.Rows[rows][column].ToString(), font8)));
PdfTable.AddCell(PdfPCell);
}
}
//PdfTable.SpacingBefore = 15f; // Give some space after the text or it may overlap the table
pdfDoc.Add(PdfTable); // add pdf table to the document
}
pdfDoc.Close();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment; filename= SampleExport.pdf");
System.Web.HttpContext.Current.Response.Write(pdfDoc);
Response.Flush();
Response.End();
//HttpContext.Current.ApplicationInstance.CompleteRequest();
}
catch (DocumentException de)
{
System.Web.HttpContext.Current.Response.Write(de.Message);
}
catch (IOException ioEx)
{
System.Web.HttpContext.Current.Response.Write(ioEx.Message);
}
catch (Exception ex)
{
System.Web.HttpContext.Current.Response.Write(ex.Message);
}
}
