Updated: See how I used Firebug to learn jQuery
2009-09-21 07:44:00
It was great to see all the positive responses to the screencast I recently recorded with Craig Shoemaker on how to use Firebug?s console to learn jQuery . That being my first screencast, I really appreciate all of your support. However, you almost unanimously commented that it was too difficult to read the commands typed at the ...### Originally posted at Encosia.

Is Silverlight the new WebForms?
2009-09-14 17:27:00
While there?s no question that HTML, CSS, and JavaScript form the foundation of modern web development, achieving fluency hasn?t been easy for everyone. In particular, the transition from stateful development with pixel-precise layout ? such as VB6 offered – has proven to be especially difficult. HTTP?s stateless nature and HTML?s relatively imprecise layout present a ...### Originally posted at Encosia.

UPDATE: We’ve recorded a higher quality version of this screencast.

Get early access to ASP.NET AJAX in Action, Second Edition
2009-08-05 15:17:00
If you?ve been reading long, you might remember that I?ve been a fan of ASP.NET AJAX in Action since the original was published. By avoiding heavy reliance on drag ?n drop methodologies, the Manning book leaves readers with a deeper understanding of the framework. Without understanding the underlying mechanisms well, developing successful solutions is as much ...### Originally posted at Encosia.

Simplify calling ASP.NET AJAX services from jQuery
2009-07-21 19:11:00
As jQuery ?s popularity in the .NET community has risen over the past year, one recurring theme I?ve seen is the desire to refactor away the details of using it to call ASP.NET AJAX services. Whether through helper function or specialized jQuery plugin, I?ve seen numerous methods proposed and/or in use. Personally, the syntax never bothered me. ...### Originally posted at Encosia.

Improving jQuery?s JSON performance and security
2009-07-07 15:00:00
When you?re working with JSON, performance and security are often opposing, yet equally important concerns. One of these areas of contention is handling the JSON strings returned by a server. Most Java Script libraries do a great job of abstracting away the details, but the underlying process has long been a frustrating exercise in compromise. On one ...### Originally posted at Encosia.

Hear me talk about jQuery on the Polymorphic Podcast
2009-06-20 19:12:00
As a longtime listener myself, I was eager when Craig asked me to come on the Polymorphic Podcast to talk about jQuery . I?ve always enjoyed how he doesn?t shy away from talking about HTML and Java Script, which is still too uncommon in the .NET world. With that in mind, I knew we?d be able to have ...### Originally posted at Encosia.

11 keystrokes that made my jQuery selector run 10x faster
2009-06-09 20:45:00
As an ASP.NET developer working on the client-side, one problem you?ll encounter is how to reference the HTML elements that ASP.NET web controls generate. All too often, you find yourself wasting time trying to reference TextBox1, when the element is actually rendered as ctl00_panel1_wizard1_TextBox1. Much has been written about this, including a post of my own, ...### Originally posted at Encosia.

As you begin developing more complex client-side functionality, managing the size and shape of your Java Script includes becomes a key concern. It?s all too easy to accidentally end up with hundreds of kilobytes of JavaScript spread across many separate HTTP requests, significantly slowing down your initial page loads.

As much as I enjoyed attending MIX09 this year, it wasn?t a difficult decision when Karsten asked me to write an article for the MIX Online site.

How I handle JSON dates returned by ASP.NET AJAX
2009-04-27 17:22:00
The problem of how to handle dates in JSON is one of the more troublesome issues that may arise when directly calling ASP.NET AJAX web services and page methods. Unlike every other data type in the language, Java Script offers no declarative method for expressing a Date. Consequently, embedding them within JSON requires a bit of fancy ...### Originally posted at Encosia.
