Dino Esposito debunks some mobile site development myths as he explains how to present users with Web pages designed to work best with their individual devices.

Find out how to use ASP.NET 2.0's site navigation controls to not only make building site navigation displays simple, but also solve real-world problems, such as hiding selected pages, or displaying "breadcrumbs."

You know you should be moving code out from behind your forms, windows and web pages and into stand-alone classes. Everyone preaches that this is what to do, everyone shows you examples of ViewModel classes, but no one really shows you a real-world example of how to get rid of the code behind.

This method, although it doesn't use binary search, handles Multiline tab pages too.private static intGetTabIndexAt( System.Windows.Forms.TabControl tabControl, System.Drawing.Point point){ int result = -1; if (tabControl != null) { for (int i = 0;...

The Razor syntax is much more than just a clean way to write ASP.NET MVC Views and WebMatrix web pages. In fact, with a working knowledge of the Razor API, you can leverage Razor templates in any application. The Razor API exposes a powerful library for parsing, compiling, and executing templates created using the Razor syntax.

I'm sure by now you've read more than your share of books and articles describing new ASP.NET 2.0 features. Master pages, themes, providers, etc., are all great, but have you read anything regarding custom Web control development and what has changed in 2.0? Well that's what I'm here to tell you. If you've become involved in control development, either through my articles or on your own, I'll describe some very cool enhancements that you can put to work right away in your controls using ASP.NET 2.0..

This article shows how to implement incremental navigation, which is a style of navigation where users find information by clicking through a series of lightweight pages, with each click resulting in a small, but highly visible change to the navigation user interface. It differs from traditional drop-down menu navigation in that incremental navigation limits the amount of new choices available to just the next level in the sitemap hierarchy.

Chances are, there are several different URLs that point to the same content on your website. For example, the URLs http://yoursite.com, http://yoursite.com/default.aspx, http://www.yoursite.com, or http://www.yoursite.com/default.aspx are all likely valid URLs that results in the same content, namely the homepage for yoursite.com. While having four different URLs reference the same content may not seem like a big deal, it can directly impact your website's search engine placement and, consequently, it's traffic. To a search engine, those four different URLs represent four different pages, even though the all produce the same content.

To understand how allowing duplicate URLs in your website can affect your search engine placement, first understand that search engines base a page's placement in the search results based, in part, on how many other websites link to the page. Now, imagine that there are 1,000 web pages from other websites that link to your homepage. You might conclude, then, that a search engine would rank the importance of your homepage based on those 1,000 links. But consider what would happen if 25% of those links linked to http://yoursite.com, 25% to http://yoursite.com/default.aspx, and so on. Rather than your homepage reflecting 1,000 inbound links, instead the search engine assumes there are only 250 links to http://yoursite.com, only 250 links to http://yoursite.com/default.aspx, and so on. In effect, redundant URLs can dilute your search engine ranking.

A key tenet of search engine optimization is URL normalization, or URL canonicalization. URL normalization is the process of eliminating duplicate URLs in your website. This article explores four different ways to implement URL normalization in your ASP.NET website.

Learn how to build applications and plug-ins that interoperate with data from OneNote 2007 and 2010 using the OneNote Object Model library freely available on CodePlex. Andy Gray demonstrates how easy it is to integrate information from OneNote notebooks, sections and pages into smart client and Web apps.

One of the most sure-fire ways to improve a web application's performance is to employ caching. Caching takes some expensive operation and stores its results in a quickly accessible location. ASP.NET version 1.0 introduced two flavors of caching:

• Output Caching - caches the entire rendered markup of an ASP.NET web page or User Control for a specified duration.
• Data Caching - a programmatically-accessible, in-memory data cache for storing objects in the web server's memory.

For a more in-depth discussion on ASP.NET 1.x's caching capabilities, refer to Scott McFarland's Caching with ASP.NET and Steve Smith's ASP.NET Caching: Techniques and Best Practices articles.

In ASP.NET 2.0, the caching system has been extended to include SQL cache dependencies, cache profiles, and post-cache substitution for output cached pages. The Caching for Performance section of the ASP.NET 2.0 QuickStarts provides a good overview of ASP.NET 2.0's caching options. This article explores output caching in ASP.NET 2.0, starting with an overview of output caching and followed by a detailed look at creating pages that include both cached and non-cached markup using fragment caching and post-cache substitution techniques.
