Dotnet Codes: Creating PDF with ASP.NET on fly

Last day I have given a situation where I have to create an HTML Invoice from database and send it through email with PDF of invoice as attachment. I found a very interesting and easy solution for this iTextPDF. A pdf library for creating pdf documents in c#.
In this example we will export grid data in PDF format and send the same by mail as PDF attachment.

default.aspx

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

</head>

<body>

<form id="form1" runat="server">

<div>

<asp:Button ID="Button1" runat="server" onclick="Button1_Click"

Text="Export To PDF" />

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"

BackColor="LightGoldenrodYellow" BorderColor="Tan" BorderWidth="1px"

CellPadding="2" ForeColor="Black" GridLines="None">

<Columns>

<asp:BoundField DataField="country_id" HeaderText="Country ID" />

<asp:BoundField DataField="country_code" HeaderText="Country Code" />

<asp:BoundField DataField="country_name" HeaderText="Country Name" />

</Columns>

<FooterStyle BackColor="Tan" />

<PagerStyle BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue"

HorizontalAlign="Center" />

<SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite" />

<HeaderStyle BackColor="Tan" Font-Bold="True" />

<AlternatingRowStyle BackColor="PaleGoldenrod" />

</asp:GridView>

</div>

</form>

</body>

</html>

string _str = _strRepeater.ToString();

//CREATE A UNIQUE NUMBER FOR PDF FILE NAMING USING DATE TIME STAMP

string filename = string.Format("{0:d7}", (DateTime.Now.Ticks / 10) % 10000000);

//CREATE DOCUMENT

Document document = new Document(new Rectangle(500f, 700f));

//SAVE DOCUMENT. CHECK IF YOU HAVE WRITE PERMISSION OR NOT

PdfWriter.GetInstance(document, new FileStream(Server.MapPath("~/pdfs/" + filename + ".pdf"), FileMode.Create));

document.Open();

List<IElement> htmlarraylist = iTextSharp.text.html.simpleparser.HTMLWorker.ParseToList(new StringReader(_str), null);

//add the collection to the document

for (int k = 0; k < htmlarraylist.Count; k++)

{

document.Add((IElement)htmlarraylist[k]);

}

document.Close();

//NOW SEND EMAIL TO USER WITH ATTACHMENT

Hi All,

Waiting for ur reply....

Hi Amit,
This you can do by using session variable (to hold the bus ticket HTML) or if you are storing the data in database then you can regenerate the data in HTML (from unique bus ticket ID) after getting the payment from user.
Hope this helps!
