A new version of Highslide JS .NET is available today. Nothing major has changed in the .NET control, but the newer Highslide JS version includes several bug fixes, compatibility improvements, and performance benefits. To eliminate one common source of confusion, I’ve decided to begin versioning Highslide JS .NET based on the version of Highslide JS embedded within the the control. For example, since this release is v4.1.4, it contains v4.1.4 of Highslide. Changes in v4.1.4 include: Updated embedded Highslide JS script version to 4.1.4. You can see what has changed in that on the Highslide.com changelog page. Added ControlBarPosition property to the HighslideManager, which allows you to position the enlargement’s control bar in any corner of the image. Added several properties (ControlBarPreviousTitle, ControlBarNextTitle, ControlBarMoveTitle, and ControlBarCloseTi... (more)

Simplify Calling ASP.NET AJAX Services From jQuery

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. The contentType parameter is ugly, but I have a Visual Studio code snippet for the $.ajax call and rarely think about it. That came to an end earlier this year, when I started using dataFilter. I needed to isolate my code from the “.d” is... (more)

A Sneak Peak at ASP.NET AJAX 4.0’s Client-Side Templating

Dave Ward's "Encosia" Blog Hot on the heels of the recent ASP.NET AJAX roadmap, Bertrand and team have released a limited preview of the new AJAX functionality coming in ASP.NET 4.0. To see how the new functionality stacks up, I decided to recreate my recent jTemplates example, using only ASP.NET AJAX and its new templating features. Eventually, I settled on using the DataView class, which offers more advanced, repeater-like functionality. Having successfully completed the exercise, I thought it seemed like something that you might find interesting too. The solution boils down to ... (more)

Improving jQuery’s JSON Performance and Security

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 JavaScript libraries do a great job of abstracting away the details, but the underlying process has long been a frustrating exercise in compromise. On one hand, eval() is the fastest widely available method, but it is not safe. On the other hand, textual JSON parsers written in JavaScript may be much safer, but are dramatically slower. In client-side situations, where milliseconds cou... (more)

Automatically minify and combine JavaScript in Visual Studio

As you begin developing more complex client-side functionality, managing the size and shape of your JavaScript 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. To combat this, it’s important to combine and compress your JavaScript. While there are useful standalone tools and HttpHandler based solutions to the problem already, none of them work quite how I prefer. Instead, I’m going to show you my dead-simple method for au...
