how to save pdf on server map path using iTextsharp

i am using following code for generate pdf and it is work perfect:
string strQuery = "select * from userdata";
SqlCommand cmd = new SqlCommand(strQuery);
DataTable dt = GetData(cmd);
//Create a dummy GridView
GridView GridView1 = new GridView();
GridView1.AllowPaging = false;
GridView1.DataSource = dt;
GridView1.DataBind();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
GridView1.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
it works good. but i am able to save this pdf to on server map path.
i have written below after pdfDoc.Close();
String path = Server.MapPath("~/mypdf.pdf");
But it is not saving pdf to server map path.
how can i do this?

You are currently writing the document to the following output stream: Response.OutputStream
Once you do pdfDoc.Close();, the PDF bytes are gone.
If you want to save the PDF to the server, then you need to replace the following line:
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
With this line:
PdfWriter.GetInstance(pdfDoc, new FileStream(context.Server.MapPath("~") + "mypdf.pdf");
Now your bytes won't be sent to the browser, but the PDF will be created on your server.

Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/pdf";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
Panel1.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
iTextSharp.text.Document pdfdoc = new iTextSharp.text.Document();
pdfdoc.SetMargins(0f, 0f, 0f, 0f);
pdfdoc.SetPageSize(iTextSharp.text.PageSize.A2);
HTMLWorker htmlparser = new HTMLWorker(pdfdoc);

Export to pdf | How to show option to open and save

I have this working code for exporting to pdf. When I export it , it asks me location to save file. Instead , I want to have option of OPEN or SAVE . Currently what I am doing is :
protected void btnPdf_Click(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=UserDetails.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
GridView2.AllowPaging = false;
GridView2.DataBind();
GridView2.RenderControl(hw);
GridView2.HeaderRow.Style.Add("width", "15%");
GridView2.HeaderRow.Style.Add("font-size", "10px");
GridView2.Style.Add("text-decoration", "none");
GridView2.Style.Add("font-family", "Arial, Helvetica, sans-serif;");
GridView2.Style.Add("font-size", "8px");
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A2, 7f, 7f, 7f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
}

If you have the file on the server
Response.TransmitFile(//FILE PATH);
If you don't
Response.BinaryWrite(//Pass Byte Array)

'The document has no page' error thrown when closing a document

I'm generating, saving and writing PDF on output stream.
I'm getting a The document has no page error while writing on output stream.
What is the problem?
string contents;
string fileName = "aaa.pdf";
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment; filename=" + fileName);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
hw.AddStyleAttribute("font-size","11px");
abs.RenderControl(hw);
string path = Server.MapPath("../Images/a.png");
contents = sw.ToString();
contents = contents.Replace("../Images/a.png", path);
sw.Close();
hw.Close();
StringReader sr = new StringReader(contents);
System.IO.FileStream fs = new System.IO.FileStream(Server.MapPath("~/pdf/") + fileName, FileMode.Create);
Document pdfDoc = new Document(PageSize.A4, 30,5,35,5);
Document cpdfDoc = new Document(PageSize.A4, 30, 5, 35, 5);
pdfDoc.PageCount = 2;
cpdfDoc.PageCount = 2;
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc,fs);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();

HTMLWorker htmlparser2 = new HTMLWorker(cpdfDoc);
PdfWriter.GetInstance(cpdfDoc, Response.OutputStream);
cpdfDoc.Open();
htmlparser2.Parse(sr);
cpdfDoc.Close();
Response.Write(cpdfDoc);
Response.Flush();
Response.End();
No problem in saving. I'm getting error on this line cpdfDoc.Close();.

use this code and set your pdf location. and image path.
its working.
string contents = "hi";
string fileName = "aaa.pdf";
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment; filename=" + fileName);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
hw.AddStyleAttribute("font-size", "11px");
string path = Server.MapPath("~/Images/a.png");
contents = contents.Replace("~/Images/a.png", path);
sw.Close();
hw.Close();
StringReader sr = new StringReader(contents);
System.IO.FileStream fs = new System.IO.FileStream(Server.MapPath("~/") + DateTime.Now.Ticks, FileMode.Create);
Document pdfDoc = new Document(PageSize.A4, 30, 5, 35, 5);
Document cpdfDoc = new Document(PageSize.A4, 30, 5, 35, 5);
pdfDoc.PageCount = 2;
cpdfDoc.PageCount = 2;
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, fs);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
fs.Close();
HTMLWorker htmlparser2 = new HTMLWorker(cpdfDoc);
PdfWriter.GetInstance(cpdfDoc, Response.OutputStream);
cpdfDoc.Open();
htmlparser2.Parse(sr);
don't use this line
contents = sw.ToString();
