Convert HTML content to PDF



How to convert HTML content to PDF? Once, this question was very intricate. But after getting the solution I found it like a piece of cake. Here, I have provided solution with C# code so that you don’t have to waste your time by looking here and there for the solutions.
I have used iTextSharp.dll (version 4.0.6.0) in my solution which is very useful indeed. You can get it from here.
Review the below code, where I have converted content of the GridView to HTML and then I have converted that HTML content into a PDF file.
I have put comments with the code for more specification.
//Include following name space to use iTextSharp library
using iTextSharp.text;
using iTextSharp.text.pdf;
//Document is inbuilt class, available in iTextSharp
Document document = new Document(PageSize.A4, 80, 50, 30, 65);
StringBuilder strData = new StringBuilder(string.Empty);
//I have provided Path for the HTML which will be generated from GridView content
string strHTMLpath = Server.MapPath("MyHTML.html");
//I have provided Path for the PDF file which will be generated from HTML content
string strPDFpath = Server.MapPath("MyPDF.pdf");
try
{
StringWriter sw = new StringWriter();
sw.WriteLine(Environment.NewLine);
sw.WriteLine(Environment.NewLine);
sw.WriteLine(Environment.NewLine);
sw.WriteLine(Environment.NewLine);
HtmlTextWriter htw = new HtmlTextWriter(sw);
//gvSearchResult is a GridView, I have converted its content to HTML and will acquire final PDF file
/*Here i have set AllowPaging and AllowSorting property of GridView as false, As my aim is to get whole content of the GridView in a single table, by setting these properties and binding the GridView again will remove paging and sorting property from it. */
gvSerchResult.AllowPaging = false;
gvSerchResult.AllowSorting = false;
BindGridView();
//Rendering the HtmlTextWriter
gvSerchResult.RenderControl(htw);
/*Here i have set AllowPaging and AllowSorting property of GridView as true, As my aim is to get whole content of the GridView is now finished and I have acquire its content in HtmlTextWriter. Then by setting properties again I will get the original form of my GridView again*/
gvSerchResult.AllowPaging = true;
gvSerchResult.AllowSorting = true;
BindGridView();
StreamWriter strWriter = new StreamWriter(strHTMLpath, false, Encoding.UTF8);
strWriter.Write("<html><head><link href=Style.css rel=stylesheet type=text/css /></head><body>" + htw.InnerWriter.ToString() + "</body></html>");
strWriter.Close();
strWriter.Dispose();
iTextSharp.text.html.simpleparser.
StyleSheet styles = new iTextSharp.text.html.simpleparser.StyleSheet();
styles.LoadTagStyle("ol", "leading", "16,0");
PdfWriter.GetInstance(document, new FileStream(strPDFpath, FileMode.Create));
document.Add(new Header(iTextSharp.text.html.Markup.HTML_ATTR_STYLESHEET, "Style.css"));
document.Open();
ArrayList objects;
styles.LoadTagStyle("li", "face", "garamond");
styles.LoadTagStyle("span", "size", "8px");
styles.LoadTagStyle("body", "font-family", "times new roman");
styles.LoadTagStyle("body", "font-size", "10px");
document.NewPage();
objects = iTextSharp.text.html.simpleparser.
HTMLWorker.ParseToList(new StreamReader(strHTMLpath, Encoding.Default), styles);
for (int k = 0; k < objects.Count; k++)
{
document.Add((IElement)objects[k]);
}
}
catch (Exception ex)
{
throw ex;
}
finally
{
document.Close();
Response.Write(Server.MapPath("~/" + strPDFpath));
Response.ClearContent();
Response.ClearHeaders();
Response.AddHeader("Content-Disposition", "attachment; filename=" + strPDFpath);
Response.ContentType = "application/octet-stream";
Response.WriteFile(Server.MapPath("~/" + strPDFpath));
Response.Flush();
Response.Close();
if (File.Exists(Server.MapPath("~/" + strPDFpath)))
{
File.Delete(Server.MapPath("~/" + strPDFpath));
}
}

How to create a countdown timer in jquery

As this jQuery library file contains the javascript functions so we need to call the function within <script> </script> tag. Now after including the file, we need to define a variable which will store that for how long you want the timer on the page(c=60) and now the time you set needs to be changed in hours , minutes and seconds using the code “ var hours = parseInt( time / 3600 ) % ;var minutes = parseInt( time / 60 ) % 60; var seconds = time % 60;” Now we need to put the condition if timer got finished (if (t
