There are basically two ways to define classes in BLOCKED SCRIPT closures, where the constructor of the class both adds methods to the new instance and provides a common context for them, and prototypes, which are the first place JavaScript will look at when looking for a member that isn't directly...

In part 1 of this post, I exposed the differences between the closure and the prototype patterns to define JavaScript classes. In this post, I'll show the shortest path to convert an existing class built using Atlas and closures to a prototype-based class. I'll also show a few caveats that you...

I'm very proud to announce that ASP.NET Ajax 1.0 shipped this morning. This is the result of all the work we've done since the first CTP and of all the very valuable feedback from our early adopters. I can't stress this enough: this product is probably one of the Microsoft products that incorporated...

This is an absolutely awesome feature. IntelliSense / autocompletion for JavaScript is a difficult problem (because of the dynamic nature of JavaScript) which the Visual Studio team is brilliantly solving. They were able to build an elegant solution to the problem that works reasonably well on plain...

The latest episode of the .NET show is all about ASP.NET Ajax. Brad and Matt first have a really interesting discussion of the history and architecture of ASP.NET Ajax and then you can see me demo-ing UpdatePanel, extenders and localization. Most of the demos are extracted from the short book Matt and...

When building Ajax applications, you basically deal with two kinds of events. First, there are DOM events , and second, events from JavaScript objects. This second category is not part of the EcmaScript specs (or of the DOM specs, of course) so each framework needs to define its own pattern to expose...

In part 1 , I showed how to subscribe to events exposed by JavaScript classes built on Microsoft Ajax. In this post, I'll show how to expose new events from your own classes. Theoretically, the only things you have to do to expose an event are to implement "add_myEvent" and "remove_myEvent" methods that...

I'm extremely pleased to announce that we're joining OpenAjax today and that I'll represent the company in the organization's meetings starting this Thursday. This is a way for us to ensure that our user community can combine the Microsoft AJAX Library and ASP.NET 2.0 AJAX Extensions...
