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...

GZip/Deflate Compression in ASP.NET MVC
Apr 1228A long while back I wrote about GZip compression in ASP.NET. In that article I describe two generic helper methods that I've used in all sorts of ASP.NET application from WebForms apps to HttpModules and HttpHandlers that require gzip or deflate compression. The same static methods also work in ASP.NET MVC. Here are the two routines: /// <summary> /// Determines if GZip is supported /// </summary> /// <returns></returns> public static bool IsGZipSupported() { string AcceptEncoding = HttpCon...

ASP.NET MVC Postbacks and HtmlHelper Controls ignoring Model Changes
Apr 1220So here's a binding behavior in ASP.NET MVC that I didn't really get until today: HtmlHelpers controls (like .TextBoxFor() etc.) don't bind to model values on Postback, but rather get their value directly out of the POST buffer. Effectively it looks like you can't change the display value of a control via model value updates on a Postback operation. To demonstrate here's an example. I have a small section in a document where I display an editable email address: This is what the form displa...

Wishful Thinking: Why can't HTML fix Script Attacks at the Source?
Apr 1215The Web can be an evil place, especially if you're a Web Developer blissfully unaware of Cross Site Script Attacks (XSS). Even if you are aware of XSS in all of its insidious forms, it's extremely complex to deal with all the issues if you're taking user input and you're actually allowing users to post raw HTML into an application. I'm dealing with this again today in a Web application where legacy data contains raw HTML that has to be displayed and users ask for the ability to use raw HTML as...

ASP.NET MVC, Web API, Razor and Open Source
Mar 1228Microsoft has made the source code of ASP.NET MVC available under an open source license since the first V1 release. We’ve also integrated a number of great open source technologies into the product, and now ship jQuery, jQuery UI, jQuery Mobile, jQuery Validation, Modernizr.js, NuGet, Knockout.js and JSON.NET as part of it. I’m very excited to announce today that we will also release the source code for ASP.NET Web API and ASP.NET Web Pages (aka Razor) under an open source license (Apache 2...

It’s The Little Things about ASP.NET MVC 4
Mar 1211Conway’s Law states, ...organizations which design systems ... are constrained to produce designs which are copies of the communication structures of these organizations. Up until recently, there was probably no better demonstration of this law than the fact that Microsoft had two ways of shipping angle brackets (and curly braces for that matter) over HTTP – ASP.NET MVC and WCF Web API. The reorganization of these two teams under Scott Guthrie (aka “The GU” which I’m contractually boun...

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...

Rebuilding CoasterBuzz, Part I: Evolution, and death to WCF
Feb 1229This is a repost from my personal blog... Last weekend, I showed a very early behind-the-scenes preview of what will eventually be the next version of CoasterBuzz (the fifth major revision in 12 years) to some folks that participated in the PointBuzz off-season tour at Cedar Point. It's very early in the process, but I thought it would be fun to talk about some of the things that have changed over the years. This series of posts probably won't mean much to non-code-monkeys, but it's fun for...

Introducing Wijmo, a feature-packed jQueryUI based widget library
Feb 1229Lately I have been evaluating a few JavaScript based UI libraries for both my projects at work and to use for a new version of the bike climbs site called 39x27.com: it was quite nice to see that almost all component vendors are now embracing, some more than others, JavaScript together with the more traditional Web Controls for ASP.NET Web Forms. In this post I’m going to briefly cover the reasons why I ended up choosing Wijmo, and then I’m giving a quick introduction on the set of widgets ...
