Here is my code for the button click to generate PDF:
{
string name = TextBox1.Text;
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=UserDetails.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Chunk c = new Chunk("Export GridView to PDF Using iTextSharp \n",FontFactory.GetFont("Verdana", 15));
Paragraph p = new Paragraph();
p.Alignment = Element.ALIGN_CENTER;
p.Add(c);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
string s = sw.ToString();
GridView1.AllowPaging = false;
BindDDL();
GridView1.RenderControl(hw);
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);
var wri = PdfWriter.GetInstance(pdfDoc, new FileStream("D:/xyz" + ".pdf", FileMode.Create));
pdfDoc.Open();
htmlparser.Parse(sr);
string contents = File.ReadAllText(Server.MapPath("~/bill.htm"));
contents = contents.Replace("[CNAME]", name);
var parsedHtmlElements = HTMLWorker.ParseToList(new StringReader(contents), null);
foreach (var htmlElement in parsedHtmlElements)
pdfDoc.Add(htmlElement as IElement);
pdfDoc.Add(p);
System.Xml.XmlTextReader xmlReader = new System.Xml.XmlTextReader(new StringReader(s));
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
}
set gridview property as follows to position it in center
<asp:GridView ID="GridView1" RowStyle HorizontalAlign="Center" ...>
m not gettin wat you exactly need...
but place your txtbox and gridview inside the table

I'm trying to convert a modal dialog with 3 DataTables to pdf using iTextSharp:
DataTable dtTable = (DataTable)ViewState["LoanPlan"];
DataTable dtTax = (DataTable)ViewState["PlanTaxData"];
DataTable dtPlan = (DataTable)ViewState["PlanAllData"];
I'm using this code to try and accomplish it:
protected void buttonPDF_Click(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
this.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
}
But it seems that it's actually trying to convert the whole .aspx page to .pdf format. How should I go about targeting just the modal dialogue or just the 3 DataTables?
I need to export data to pdf file ,
but I have `An exception of type
System.OutOfMemoryException' occurred in mscorlib.dll but was not handled in user code
this is my Code
using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter hw = new HtmlTextWriter(sw))
{
GridView ExportGrid = new GridView();
ExportGrid.AllowPaging = false;
List<Tayf.Models.Product> DataLst = new List<Tayf.Models.Product>();
DataLst = HttpContext.Current.Cache["productcache"] as List<Tayf.Models.Product>;
ExportGrid.DataSource = DataLst;//DataSet1 has all values without paging
ExportGrid.AllowPaging = false;
ExportGrid.DataBind();
ExportGrid.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);
pdfDoc.Close();
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=GridViewExport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Write(pdfDoc);
Response.End();
}
}
my data is Very huge over than 1 million row and I need to export all data in one file
As your data is such big, maybe you should separate your data into many parts and write them into the pdf separately.
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.
I used the following code to export div content to pdf format using itextsharp
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
Panel1.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
// Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
Document pdfDoc = new Document(new Rectangle(1000f, 1000f));
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
it shows the following error
Could not find a part of the path 'C:\Program Files\Common Files\Microsoft Shared\DevServer\10.0\Images\logo.png'.`
if i hide the logo in desin then it exported to pdf but the alignment are missing. how to correct it.The page i need to export is follows
In order to export the content to any pdf file, you need to follow the basic conventions of pdf file, those are given in the appendix G of the following pdf reference,
http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_reference_1-7.pdf
Firstly install class in Nuget console: Install-Package itextsharp.xmlworker
Then add namespace: using iTextSharp.tool.xml;
Response.ContentType = "application/pdf";
//string pdf;
// pdf = Convert.ToInt32(hidTablEmpCode.ToString()).ToString() + ".Pdf";
Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
//Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
// var example_html = #"<p>This is <span class="" headline="" style="">some</span> sample text<span style="">!!!</span></p>";
StringReader sr = new StringReader(lblMessageDetail.Text);
Document pdfDoc = new Document(PageSize.A4, 50f, 50f, 50f, 50f);
var writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
for (int i = 0; i < 5; i++)
{
string imageFilePath2 = Server.MapPath(".") + "/images/GraphicNew.jpg";
iTextSharp.text.Image jpg3 = iTextSharp.text.Image.GetInstance(imageFilePath2);
jpg3.Alignment = iTextSharp.text.Image.UNDERLYING;
jpg3.ScaleToFit(3530, 835);
jpg3.SetAbsolutePosition(0, 0);
pdfDoc.Add(jpg3);
}
XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);
string imageFilePath = Server.MapPath(".") + "/Bimages/ns5.png";
iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageFilePath);
GetEmp();
string imageURLS = Server.MapPath("~/Emp/Document/") + hidTablEmpCode.Value + "/" + hidSign.Value.ToString();
iTextSharp.text.Image jpg2 = iTextSharp.text.Image.GetInstance(imageURLS);
jpg2.ScaleToFit(100, 50);
jpg2.SetAbsolutePosition(370, 530);
jpg2.Alignment = Element.ALIGN_LEFT;
pdfDoc.Add(jpg2);
jpg.Alignment = iTextSharp.text.Image.ALIGN_LEFT;
jpg.ScaleToFit(100, 50);
jpg.SetAbsolutePosition(50, 735);
pdfDoc.Add(jpg);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
i am trying to export my HTML page to PDF using iTextSharp lib. firstly i am trying to print table which is in my Aspx page.PDF is created successfully but there nothing in PDF.
i am using this code below :
protected void btnExportToPdf_Click(object sender, EventArgs e)
{
btnExportToPdf.Visible = false;
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=TestPage.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
exportTable.RenderControl(hw);
//this.Page.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End(); }
Now I'm not too seasoned, but the problem to me looks like you are never actually writing the strings to the file. I see a few different string objects you initialize, and I see you adding the HTML to it, but I never see you actually write them to the PDF. This is my usual process for parsing HTML to PDF, maybe you can look at it, and see what you are missing.
System.Text.StringBuilder store = new System.Text.StringBuilder();
string line;
while ((line = htmlReader.ReadLine()) != null)
{
store.Append(line + Environment.NewLine);
}
string html = store.ToString();
FileStream stream = new FileStream(newFileName, FileMode.Create, FileAccess.Write);
Document document = new Document(PageSize.LETTER, 15, 15, 35, 25);
PdfWriter writer = PdfWriter.GetInstance(document, stream);
document.Open();
System.Collections.Generic.List<IElement> htmlarraylist = new List<IElement>(HTMLWorker.ParseToList(new StringReader(html), new StyleSheet()));
foreach (IElement element in htmlarraylist)
{
document.Add(element);
}
document.Close();
That was what jumped out to me at least, was the fact that it doesn't look like you actually write the generated text to the PDF. I hope this helps.
