It has been more than a year since the last time we discussed WebAPI with WebForms, and a lot has changed in that time. Microsoft has released a 1.0 release of WebAPI and Telerik now supports using WebAPI as a client-side datasource for many of our controls. In this article, I will show you how to configure WebAPI to work with one of Telerik’s most popular controls, our Grid for ASP.NET AJAX. Without changing the appearance of the grid, I will convert the grid from server-side databinding to client-side databinding and show you how it supports sorting, filtering and paging with WebAPI.

I’ve been noticing that people use the word “callback” for almost any request to the server, but in ASP it has its own meaning and there are many other ways to call the server. So, I wanted to make a few clarifications and a quick list.

JSON (JavaScript Object Notation) is the way to handle data on the client these days. It really is the cat’s pajamas. Almost all the client-side widgets or libraries that you’ll be working with will most likely be utilizing JSON, and sending large chunks of data over the wire as JSON as opposed to other bulky forms of data can lead to some dramatic performance increase across any application. I often come across individuals not sure of what JSON is, or how they can use it today, and I wanted to address this issue in a blog post. Of course I...

In my last blog I introduced the basics of using ASP.NET AJAX and WebAPI together in the same project.  In addition, I showed how to bind results from WebAPI to a Telerik’s ASP.NET AJAX Grid. In this blog I will continue down this path and implement insert, update, and delete operations using WebAPI and RadGrid!

Note: While this post focuses on using WebAPI in conjunction with RadGrid, most of the client code can be used when working with RadGrid in client mode.

With the introduction of MVC 4 Microsoft has created a fantastic new way for developers to expose data via HTTP service.  WebAPI is extremely easy to configure when compared to WCF services, and can send content in a multitude of formats.  On top of that you can easily extend it at almost any level.  While WebAPI shipped with MVC 4, it can easily be used in Asp.Net AJAX as well!  In this blog we will take a look at setting up WebAPI in ASP.Net Web Forms
