Over Christmas, I had a bit of spare time, so I decided to add some functionality to this site. One of the things that I added was the ability for people to post comments about specific articles, and you will see that a form has been added at the end of this article. The other thing I have been meaning to get round to is to add a Google Site Map. I believe I have created my site to be as friendly to Google's bots as possible, but there is no harm in submitting a site map to guarantee that Google knows about all the pages I want indexed.

Delegates in C# cause a fair amount of confusion, but with the introduction of LINQ to SQL and the profilic use of the Lambda Expression operator (=>) that it has foisted on an unprepared batch of beginners, an understanding of how these two items are related, together with Anonymous Methods becomes more important. Most definitions of Delegates that you find start off with comparing them to "function pointers in C or C++", which is great if you ever worked with those languages and understood them, but not helpful to new programmers. Here's my attempt at simplifying the various concepts.

Many times, I have seen questions about where to obtain Charting controls for ASP.NET web applications, and until recently, the answer has always been to have a look at many of the third party offers that are available from the leading control development companies. That is until Microsoft released their Chart Controls for both Windows Forms and ASP.NET to work with .Net 3.5 SP1.

Tables will probably be one of the most used elements in PDFs generated from ASP.NET applications to provide the structure for documents such as orders and invoices. This overview is not an exhaustive examination of tables, but provides an introduction to working with them through iTextSharp, and builds on the previous articles in this iTextSharp series:

Over the years, I have picked up and read many Beginners books that attempt to get someone started on the road to building web sites with ASP.NET. Nearly all of them assumed that their readers know more than they might. Some of them seem to assume that all readers are upgrading from one version of the .NET framework to another, while others assume that you already know about core web development technologies such as HTML, CSS, C# or VB etc. I well remember being frustrated with my first book, in that it didn't give me enough basic information to get started with web development, let alone web development with ASP.NET. Now, up steps Imar Spaanjaars, with his effort: Beginning ASP.NET 3.5 in C# and VB (Wiley/Wrox, ISBN: 978-0-470-18759-3).

Interactivity within PDF documents is enabled though Anchors (links) and Bookmarks. Following earlier articles in my iTextSharp series, this particular contribution will introduce the basics of linking and bookmarking PDF documents created via iTextSharp.

This is the third in a series of articles that looks at using the open source component, iTextSharp from within ASP.NET to generate PDFs. Just as HTML and ASP.NET provide containers for varying ampounts of textual content, iTextSharp offers the Chunk, Phrase and Paragraph classes. Before going on, if you would like to read earlier articles, they are:

Following on from my introduction to iTextSharp, the free PDF utility that lets you work with PDF files within ASP.NET, this article looks at working with fonts in PDF documents that you create. If you haven't read the first article in this series, I recommend that you do so now.

The .NET framework does not contain any native way to work with PDF files. So, if you want to generate or work with PDF files as part of your ASP.NET web application, you will have to rely on one of the many third party components that are available. Google will help you to find one that fits your budget, as well as a range of open-source free components. One of the free components is iTextSharp, which is a port of a well known Java utility, iText.
