ASP.NET web services mistake: manual JSON serialization

Wed, 13 Apr 2011 18:25:34 GMT

If you've spent much time working with the .NET platform, ASP.NET's simple, convention-based approach to exposing JSON endpoints seems just about too good to be true. After years of fiddling with manual settings in XML configuration files, it's understandable to assume that working with JSON in ASP.NET would require a similar rigmarole, yet it does not. Unfortunately, this unexpected ease-of-use isn't obvious if you don't already know about it, which has led some developers to build needlessly complicated solutions to problems that don't actually exist. In this post, I want to point out a few ways not to approach JSON in ASP.NET and then show you a couple examples of leveraging the frame work to do it "right".

How to pass Dictionary as a parameter to an ActionResult

Fri, 03 Jul 2009 20:48:07 GMT

I'm using jQuery to make an Ajax call using an Http Post in ASP.NET MVC. I would like to be able to pass a Dictionary of values. I finally figured out the best solution is to pass JSON via the Http Post and use a custom ModelBinder to convert the JSON to a Dictionary. One thing I did in my solution is created a JsonDictionary object that inherits from Dictionary so that I can attach the custom ModelBinder to the JsonDictionary type, and it wont cause any conflicts in the future if I use Dictionary as a ActionResult parameter later on for a different purpose than JSON.

Update Panels and JSON Alternatives

Sun, 31 May 2009 17:32:48 GMT

In most asp.net applications users experience post backs as a result of submit action by the client browsers. These post backs can be quite annoying when just a small part of the page needs to be refreshed. Update panels are designed to perform partial post back eliminating the need for doing a complete post back for updating a part of the page. But are these post backs truly partial? In this article we try to find out if Update panels actually improve performance by doing partial post backs or do they end up degrading it.

Using JsonResult in ASP.NET MVC AJAX

Sat, 27 Dec 2008 19:31:02 GMT

In ASP.NET MVC you can write action methods that return a variety of types to be used in your views to obtain data for AJAX interactions. Most common types are string and ActionResult, but there is also an option called JsonResult which returns its values as JSON serialized data. The returned data can be used easily in client-side as appropriate.
