Passing multiple POST parameters to Web API Controller Methods
May 1209ASP.NET Web API introduces a new API for creating REST APIs and making AJAX callbacks to the server. This new API provides a host of new great functionality that unifies many of the features of many of the various AJAX/REST APIs that Microsoft created before it - ASP.NET AJAX, WCF REST specifically - and combines them into a whole more consistent API. Web API addresses many of the concerns that developers had with these older APIs, namely that it was very difficult to build consistent REST sty...

Dynamic JSON Parsing in .NET with JsonValue
Mar 1219So System.Json has been around for a while in Silverlight, but it's relatively new for the desktop .NET framework and now moving into the lime-light with the pending release of ASP.NET Web API which is bringing a ton of attention to server side JSON usage. The JsonValue, JsonObject and JsonArray objects are going to be pretty useful for Web API applications as they allow you dynamically create and parse JSON values without explicit .NET types to serialize from or into. But even more so I think...

Using an alternate JSON Serializer in ASP.NET Web API
Mar 1209The new ASP.NET Web API that Microsoft released alongside MVC 4.0 Beta last week is a great framework for building REST and AJAX APIs. I've been working with it for quite a while now and I really like the way it works and the complete set of features it provides 'in the box'. It's about time that Microsoft gets a decent API for building generic HTTP endpoints into the framework. DataContractJsonSerializer sucks As nice as Web API's overall design is one thing still sucks: The built-in JSON S...

Using the HTML5 <input type="file" multiple="multiple"> Tag in ASP.NET
Mar 1206Per HTML5 spec the <input type="file" /> tag allows for multiple files to be picked from a single File upload button. This is actually a very subtle change that's very useful as it makes it much easier to send multiple files to the server without using complex uploader controls. Please understand though, that even though you can send multiple files using the <input type="file" /> tag, the process of how those files are sent hasn't really changed - there's still no progress information or oth...

Using the West Wind Web Toolkit to set up AJAX and REST Services
Nov 1103I frequently get questions about which option to use for creating AJAX and REST backends for ASP.NET applications. There are many solutions out there to do this actually, but when I have a choice - not surprisingly - I fall back to my own tools in the West Wind West Wind Web Toolkit. I've talked a bunch about the 'in-the-box' solutions in the past so for a change in this post I'll talk about the tools that I use in my own and customer applications to handle AJAX and REST based access to servic...

Custom Model Binder for binding drop downs into a DateTime in MVC
Jul 1106I have a Nullable DateTime Property in my Model I want to bind painlessly with three drop down select boxes I have for Day Month and Year respectively. First thing to do is to make a new shiny custom model binder. I have done mine by inheriting from DefaultModelBinder (which you will need to include System.Web.Mvc to access). using System; using System.ComponentModel; using System.Web.Mvc; namespace Infrastructure.OFP.ModelBinders { public class MyUserModelBinder : DefaultModelBinder { protect...

Mix 11 - Web Platform and Tools Keynote Demo Script
Apr 1113It's Day 1 of the Mix 11 conference here in Las Vegas. I work for the Web Platform and Tools (that's ASP.NET, IIS, IIS Media, etc) group and I did the Web Platform demos for Scott Guthrie's part of the keynote. A lot of people in Dev and QA worked hard all year long to make some fun and cool products and as the designated talking head, I had just 16 minutes to make all of them (people + products) look good. I hope I did them all justice. We built a backend and a front end for Rob and my sie...
