In the following code, Parse cannot take StringReader (sr) as input. How can I pass the string I have to Parse, then?
protected void LinkButton1_Click(object sender, EventArgs e)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=UserDetails.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
string str = "<h1 title=’Header’ align=’Center’> Writing To PDF Using ASP.NET> <br><table align=’Center’><tr><td style=’width:100px;color:green’> <b>iTextSharp</b></td><td style=’width:100px;color:red’>mytestpdf</td></tr></table>";
StringReader sr = new StringReader(str);
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0.0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);//Parse cannot take input as string reader (sr) how to solve?
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
}
Why are you putting your html into a StringReader? You already have the html in a string, just use that.
htmlparser.Parse(str)
If you must use StringReader for some reason, use the ReadToEnd() method to get a data type HTMLWorker.Parse will accept:
htmlparser.Parse(sr.ReadToEnd())
I update the itextsharp 5.0.. ..
now it not showing errors..

I am getting error at htmlparser.Parse(sr).
Thanks in advance

Add DivMaster (div) in design page and Add ur HTML code inside that DivMaster.
Note: Use % or px throughout HTML design.
i have a header at the top of my front page like this:
i use iTextSharp code to generate its PDF ... but the resulting PDF do not contain this Header with black : instead some CSS is written in place of header like this:
How can i possibly fix this issue??
Code:
protected void BtnPDF_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.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();
}
Have you tried to use inline css? Because HTML/CSS parser in iTextSharp is not complete. So it may not work as you want.
Also check out the LoadTagStyle property of StyleSheet in iTextSharp, see if it helps.
For more details about it, see this answer: https://stackoverflow.com/a/9616429/604232
I have one Gridview in my asp .Net project (c#) and i want to export it to pdf
for this purpose i'm using iTextSharp as bellow:
public override void VerifyRenderingInServerForm(Control control)
{ /* Do nothing */ }
protected void Button2_Click1(object sender, EventArgs e)
{
Response.Clear(); //this clears the Response of any headers or previous output
Response.Buffer = true; //ma
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=DataTable.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
ASPxGridView1.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();
}
when i test it , i get this error:
The UNC path should be of the form \server\share
anybody pls help me?
This is my code :
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.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);** //the exception here
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
the error is :
Unable to cast object of type 'iTextSharp.text.html.simpleparser.CellWrapper' to type
'iTextSharp.text.Paragraph'.
What is this exception ?
I don't know if this is the answer, but I found that iTextSharp is picky about having valid html. My tests had a table that was opened twice and never closed and that took about an hour for me to notice. The exception was very similar to the one you have there.
use can you A4 size width & height for html deigning .
use this set od code to create pdf from html.
String htmlText = "<div>Your HTML text here</div>";
Document document = new Document();
PdfWriter.GetInstance(document, new FileStream(Request.PhysicalApplicationPath + "\\outfile.pdf", FileMode.Create));
document.Open();
iTextSharp.text.html.simpleparser.StyleSheet styles = new iTextSharp.text.html.simpleparser.StyleSheet();
iTextSharp.text.html.simpleparser.HTMLWorker hw = new iTextSharp.text.html.simpleparser.HTMLWorker(document);
hw.Parse(new StringReader(htmlText));
document.Close();
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("Content-Disposition", "inline;filename=outfile.pdf");
Response.ContentType = "application/pdf";
Response.WriteFile(Request.PhysicalApplicationPath + "\\outfile.pdf");
Response.Flush();
Response.Clear();
