As I mentioned in another post, AJAX is used to make web pages more interactive and responsive. We saw that the UpdatePanel control is an easy way of adding AJAX to a web page. But there are times when an operation can’t be completed quickly, so to the user it might seem like nothing is […]

The Microsoft Chart control allows us to easily create many types of charts in Windows applications and in ASP.NET applications. If you’re using .NET 3.5 (Visual Studio 2008), you will need to download a separate installer from Microsoft’s download page.

jQuery is the default AJAX library when you create a new ASP.NET Web Application or ASP.NET MVC Web Application in Visual Studio 2010.

No matter how complex a web page looks, the process is always the same: the browser sends a request to the server, and the server sends a response back. It’s part of the HTTP protocol. Even AJAX uses the same principle. A servlet is a Java class capable of processing a request and generating a […]

In the previous post, we created a page that’s able to call a web service from ASP.NET AJAX. In that sample we displayed a list of locations close to a zip code. It would be very useful to also show a map to the user with the found locations, and thanks to Google Maps JavaScript […]

The power of AJAX is the capability of calling the web server and updating only a portion of the page using JavaScript. Besides calling code in the page itself, as it occurs when using the UpdatePanel, we can also call a web service with ASP.NET AJAX. In this post, we’ll build a small page that […]
