I have rendered my aspx page to pdf successfully using ITextSharp.
Now i want to add watermark logo in background off PDF file please help me out i have been stuck into this.
Following is my code for export to pdf
private void ShowPdf(string s)
{
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("Content-Disposition", "inline;filename=" + s);
Response.ContentType = "application/pdf";
Response.WriteFile(s);
Response.Flush();
Response.Clear();
}
public void PrepareControlForPDF()
{
MemoryStream mem = new MemoryStream();
StreamWriter twr = new StreamWriter(mem);
HtmlTextWriter myWriter = new HtmlTextWriter(twr);
divApplicantDetails.RenderControl(myWriter);
myWriter.Flush();
// myWriter.Dispose();
StreamReader strmRdr = new StreamReader(mem);
strmRdr.BaseStream.Position = 0;
string pageContent = strmRdr.ReadToEnd();
//CreatePDFDocument(strmRdr);
//strmRdr.Dispose();
///mem.Dispose();
CreatePDFDocument(pageContent);
//writer.Write(pageContent);
}
public void CreatePDFDocument(string strHtml)
{
string filename = ""+System.DateTime.Now.Day+"AppLetter.pdf";
// if (System.IO.File.Exists(Server.MapPath("../Pdf") + "/" + filename))
// {
// System.IO.File.Delete(Server.MapPath("../Pdf") + "/" + filename);
// }
string strFileName = Server.MapPath("../Pdf") + "/" + filename;
Document document = new Document();
try
{
PdfWriter.GetInstance(document, new FileStream(strFileName, FileMode.Create));
StringReader se = new StringReader(strHtml);
MemoryStream ms = new MemoryStream();
ms.Write(System.Text.Encoding.ASCII.GetBytes(strHtml), 0, System.Text.Encoding.ASCII.GetBytes(strHtml).Length);
//ms.Position = 0;
StreamReader sr = new StreamReader(new MemoryStream(new System.Text.ASCIIEncoding().GetBytes(strHtml)));
sr.BaseStream.Position = 0;
HTMLWorker obj = new HTMLWorker(document);
document.Open();
obj.Parse(se);
}
finally
{
document.Close();
}
}
I think you can achieve by creating a new class and implementing the IPdfPageEvent interface... refer here

Can anyone tell me how can I create a pdf file using iTextSharp 7 and popup a save dialog instead of saving it to a specific disk location?
My test code is the following:
protected void btnPrint_OnClick(object sender, EventArgs e)
{
Document doc = new Document(PageSize.A4, 25f, 20f, 20f, 10f);
var output = new FileStream(Server.MapPath("MyFirstPDF.pdf"), FileMode.Create);
var writer = PdfWriter.GetInstance(doc, output);
doc.Open();
doc.Add(new Paragraph("test!"));
doc.Close();
}
The workaround I found is the following:
After creating the document:
string path = "C:\\...";
string fileName = "PdfFile.pdf";
FileInfo fileInfo = new FileInfo(path);
Byte[] FileBuffer = File.ReadAllBytes(fileInfo.FullName);
if (FileBuffer != null)
{
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName);
Response.AddHeader("content-length", FileBuffer.Length.ToString());
Response.BinaryWrite(FileBuffer);
Response.Flush();
//DELETE FILE AFTER DOWNLOAD
fileInfo.Delete();
Response.End();
}
I have a web application developed in ASP.NET. I am using rdlc to do the reporting. Everything seems to work fine on my development machine, but not when I upload the application to the hosting service (GoDaddy.com). The reports show up as preview (ReportViewer Control). But when I click on Print it is not showing the preview.
public void print()
{
try
{
Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string extension;
byte[] bytes = ReportViewer1.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamids, out warnings);
FileStream fs = new FileStream(HttpContext.Current.Server.MapPath("output.pdf"), FileMode.Create);
fs.Write(bytes, 0, bytes.Length);
fs.Close();
//Open exsisting pdf
Document document = new Document(PageSize.A4);
PdfReader reader = new PdfReader(HttpContext.Current.Server.MapPath("output.pdf"));
//Getting a instance of new pdf wrtiter
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(HttpContext.Current.Server.MapPath("Print.pdf"), FileMode.Create));
document.Open();
PdfContentByte cb = writer.DirectContent;
int i = 0;
int p = 0;
int n = reader.NumberOfPages;
Rectangle psize = reader.GetPageSize(1);
float width = psize.Width;
float height = psize.Height;
//Add Page to new document
while (i < n)
{
document.NewPage();
p++;
i++;
PdfImportedPage page1 = writer.GetImportedPage(reader, i);
cb.AddTemplate(page1, 0, 0);
}
//Attach javascript to the document
PdfAction jAction = PdfAction.JavaScript("this.print(true);\r", writer);
writer.AddJavaScript(jAction);
document.Close();
//Attach pdf to the iframe
frmPrint.Attributes["src"] = "Print.pdf";
}
catch (Exception ex)
{
Response.Write("<script>alert('Error Occured')</script>");
}
}
I am using the above code for print..
I am trying to export data in a Gridview to Excel and store that file in a folder on server.
I have done this part. The only thing I want to do is,
I want to prevent downloading the Excel file.
Please find my code below.
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "order.xls"));
Response.ContentType = "application/ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gridX.AllowPaging = false;
bindX();
gridX.HeaderRow.Style.Add("background-color", "#FFFFFF");
for (int i = 0; i < gridX.HeaderRow.Cells.Count; i++)
{
gridX.HeaderRow.Cells[i].Style.Add("background-color", "#df5015");
}
gridX.RenderControl(htw);
//Response.Write(sw.ToString());
string renderedGridView = sw.ToString();
string path = Server.MapPath("~/Order/od/x");
System.IO.File.WriteAllText(path + "/order" + lblF.Text + ".xls", renderedGridView);
sw.Close();
htw.Close();
Thanks in advance.
Use this code by editing as per your need :
private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
e.Cancel = true;
WebClient client = new WebClient();
client.DownloadDataCompleted += new DownloadDataCompletedEventHandler(client_DownloadDataCompleted);
client.DownloadDataAsync(e.Url);
}
void client_DownloadDataCompleted(object sender, DownloadDataCompletedEventArgs e)
{
string filepath = textBox1.Text;
File.WriteAllBytes(filepath, e.Result);
MessageBox.Show("File downloaded");
}
Hope this will help you.
I got the answer.
Code
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gridX.AllowPaging = false;
bindX();
gridX.HeaderRow.Style.Add("background-color", "#FFFFFF");
for (int i = 0; i < gridX.HeaderRow.Cells.Count; i++)
{
gridX.HeaderRow.Cells[i].Style.Add("background-color", "#df5015");
}
gridX.RenderControl(htw);
//Response.Write(sw.ToString());
string renderedGridView = sw.ToString();
string path = Server.MapPath("~/Order/od/x");
System.IO.File.WriteAllText(path + "/order" + lblF.Text + ".xls", renderedGridView);
sw.Close();
htw.Close();
protected void txt_btn_Click(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=TestResult.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringBuilder htmlText = new StringBuilder();
htmlText.Append("<table style='color:red;' border='1'><tr><th>createing pdf</th><tr><td> abcdef</td></tr></table>");
StringReader stringReader = new StringReader(htmlText.ToString());
Document doc = new Document(PageSize.A4);
List<iTextSharp.text.IElement> elements =
iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(stringReader, null);
doc.Open();
foreach (object item in elements)
{
doc.Add((IElement)item);
}
doc.Close();
// Response Output
PdfWriter.GetInstance(doc, Response.OutputStream);
doc.Open();
//doc.Close();
Response.Write("PDF is created");
}
}
I am try to create pdf file.But pdf is created only 0kb.Mean when i open this it's shw error that May be pdf damaged
I'm assuming that you are using iTextSharp library.
private void GeneratePDF()
{
try
{
string pdfPath = "~/PDF/File_1.pdf";
StringBuilder sb = new StringBuilder();
sb.Append("Name : chamara" + Environment.NewLine);
sb.Append("Address : sri lanaka" + Environment.NewLine);
sb.Append("Institute : SLIIT" + Environment.NewLine);
Document doc = new Document();
PdfWriter.GetInstance(doc, new FileStream(Server.MapPath(pdfPath), FileMode.Create));
doc.Open();
doc.Add(new Paragraph(sb.ToString()));
doc.Close();
}
catch (Exception ex)
{
throw ex;
}
}
I use Sharepoint 2010 and I am developing a web part where on a button click event, a pdf file needs to be generated and opened directly. Should not be saving onto the disk.
I tried the below code
protected void Button1_OnClick(object sender, EventArgs e)
{
Document myDoc = new Document(PageSize.A4.Rotate());
try
{
PdfWriter.GetInstance(myDoc, new FileStream(#"C:\Directory\Test.pdf", FileMode.Create));
myDoc.Open();
myDoc.Add(new Paragraph("Hello World"));
}
catch (DocumentException ex)
{
Console.Error.WriteLine(ex.Message);
}
myDoc.Close();
}
I also tried the below code which also generates the file on the Server which I dont want.
Document document = new Document(PageSize.A4);
PdfWriter.GetInstance(document, new FileStream(HttpContext.Current.Server.MapPath("~/Test.pdf"), FileMode.Create));
document.Open();
var WelcomePara = new Paragraph("Hello World");
document.Add(WelcomePara);
document.Close();
This one creates the pdf file on the desktop, I need it to be opened in the pdf format.Can someone help me please.
Almost every time that something accepts a FileStream is actually really accepts a generic System.IO.Stream object which FileStream is a subclass of. This means that you can instead use its cousin System.IO.MemoryStream which is what you are looking for:
byte[] bytes;
using (System.IO.MemoryStream ms = new System.IO.MemoryStream()) {
using (iTextSharp.text.Document doc = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4.Rotate())) {
using (iTextSharp.text.pdf.PdfWriter w = iTextSharp.text.pdf.PdfWriter.GetInstance(doc, ms)) {
doc.Open();
doc.NewPage();
doc.Add(new iTextSharp.text.Paragraph("Hello world"));
doc.Close();
bytes = ms.ToArray();
}
}
}
//Do whatever you want with the byte array here
You don't have to create the byte array if you don't want, I was just showing how to create a PDF and give you something ".net-like" for you to work with.
I was able to get it work finally.
using (var ms = new MemoryStream())
{
using (var document = new Document(PageSize.A4,50,50,15,15))
{
PdfWriter.GetInstance(document, ms);
document.Open();
document.Add(new Paragraph("HelloWorld"));
document.Close();
}
Response.Clear();
//Response.ContentType = "application/pdf";
Response.ContentType = "application/octet-stream";
Response.AddHeader("content-disposition", "attachment;filename= Test.pdf");
Response.Buffer = true;
Response.Clear();
var bytes = ms.ToArray();
Response.OutputStream.Write(bytes, 0, bytes.Length);
Response.OutputStream.Flush();
}
This Works for me.
using (var ms = new MemoryStream())
{
using (var document = new Document(PageSize.A4,50,50,15,15))
{
// step 2
PdfWriter writer = PdfWriter.GetInstance(document, ms);
// step 3
document.Open();
// XML Worker
XMLWorker worker = new XMLWorker(css, true);
XMLParser p = new XMLParser(worker);
p.Parse(new StringReader(--Your HTML--));
// step 5
document.Close();
}
Byte[] FileBuffer = ms.ToArray();
if (FileBuffer != null)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", FileBuffer.Length.ToString());
Response.BinaryWrite(FileBuffer);
}
}
