ASP.NET is an open-source server-side web-application framework designed for web development to produce dynamic web pages developed by Microsoft to allow programmers to build dynamic web sites, applications and services.
iTextSharp (now iText) is a library for creating and manipulating PDF files in Java and .NET. iText was written by Bruno Lowagie. The source code was initially distributed as open source under the Mozilla Public License.
In this article, I will show you how to convert ASP.NET GridView control to pdf at runtime.

ReplyDelete@Rima Gandhi:Inherit your base page class with newly created class MyPage
ReplyDeleteThe above code is good enough to convert a HTML code but i guess you can easily use the new itextShapr library's HTML worker class to make the task even easier. It automatically parses all HML and gives you the PDF. The main loophole is the IMG tag;s relative URLs and it can be taken care by your code. I have written the code and ahred it here (if anybody would like to use it):
