In this article we'll see how easy it is to use Virtual Earth SDK to produce a simple mashup, using web services that provide information in JSON format. Live Demo - Source Code If you are not familiar with JSON or how to integrate JSON services in ASP.NET AJAX applications, you can take a look at my 3-part series of articles on JSON and ASP.NET AJAX here. First of all, we need to create a simple .aspx page, and add a ScriptManager to it. Then, we're going to reference the Virtual Earth API in the...

This is the third part of a series of articles on ASP.NET AJAX and JSON. If you haven't read part 1 and part 2 of this series, you are strongly advised to do so before going on to read this article. Let's take what we've seen so far on JSON and ASP.NET one step further, and discover how we can leverage the ASP.NET AJAX infastructure to make the managing of an AJAX application even sleeker. Now, let's imagine that we want to elaborate the JSON response returned from the web service before sending...

Now, after the very futile example which accompanied the introduction to JavaScript Object Notation in my last post (by the way, I forgot to mention that this is what the fancy acronym stands for, but I'm sure you already knew that), let's go straight to the fun part, and see how we can leverage the flexibility of JSON (and ASP.NET AJAX, of course) to achieve some less trivial result. When developing a web application, we often need to aggregate data from different sources. You might argue this is...

If you are a web developer, and you haven't been living under a rock for most of the past year, you must at least have heard of JSON. In the wake of the tremendous hype relating to everything even vaguely AJAX-related, JSON has climbed in record time the list of the top 10 technologies a web developer has to master. Let's make it clear from the start: JSON does deserve a top spot in such a list, if nothing else because it's the skeleton that keeps the whole AJAX paradigm on its feet. Even more so...
