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...

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...

Physical Directories vs. MVC View Paths
Apr 1205This post falls into the bucket of operator error on my part, but I want to share this anyway because it describes an issue that has bitten me a few times now and writing it down might keep it a little stronger in my mind. I've been working on an MVC project the last few days, and at the end of a long day I accidentally moved one of my View folders from the MVC Root Folder to the project root. It must have been at the very end of the day before shutting down because tests and manual site nav...

Rebuilding CoasterBuzz, Part III: The architecture using the "Web stack of love"
Apr 1203This is the third post in a series about rebuilding one of my Web sites, which has been around for 12 years. I hope to relaunch in the next month or two. More: Part I: Evolution, and death to WCF Part II: Hot data objects I finally hit a point in the re-do of CoasterBuzz where I feel like the major pieces are in place... rewritten, ported and what not, so that I can focus now on front-end design and more interesting creative problems. I've been asked on more than one occasion (OK, just...

Rebuilding CoasterBuzz, Part II: Hot data objects
Mar 1219This is the second post, originally from my personal blog, in a series about rebuilding one of my Web sites, which has been around for 12 years. More: Part I: Evolution, and death to WCF After the rush to get moving on stuff, I temporarily lost interest. I went almost two weeks without touching the project, in part because the next thing on my backlog was doing up a bunch of administrative pages. So boring. Unfortunately, because most of the site's content is user-generated, you need some...

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...

Abstracting away issues of HttpContext from your ASP.NET MVC controllers
Feb 1203I've noticed that I write software in one of three modes: For myself: Shortcuts, less testing, not well-factored. For myself but in public: Mostly POP Forums, which I try to avoid letting it suck since others will use it and see the code. For sharing: Any day job or gig where others will use or maintain your code. You don't want to unleash crapsauce on others. I have to admit that second case isn't the most clean of endeavors. While I'm generally happy with the forum app and the feedba...

The evolution of asynchronous controllers in ASP.NET MVC
Jan 1209Asynchronous operations in ASP.NET MVC have always been left a bit behind. They appeared in ASP.NET MVC 2, remained untouched in v3, but now in MVC 4 (especially in combination with C# 5 and async/await) they reached the same easiness of use of the standard synchronous controller. Now (or better, in a few months with the release of ASP.NET MVC 4, .NET 4.5 and C# 5) you can write public async Task<ViewResult> Stuff() { return View(await DoStuff("Some stuff")); } In this post I’m going to...

XmlWriter and lower ASCII characters
Jan 1202Ran into an interesting problem today on my CodePaste.net site: The main RSS and ATOM feeds on the site were broken because one code snippet on the site contained a lower ASCII character (CHR(3)). I don't think this was done on purpose but it was enough to make the feeds fail. After quite a bit of debugging and throwing in a custom error handler into my actual feed generation code that just spit out the raw error instead of running it through the ASP.NET MVC and my own error pipeline I foun...

Set the AsyncTimeout attribute for your async controllers
Dec 1107Today I decided to convert an action that was making various long calls to external webservices to be asynchronous. With the synchronous version it was long but still under the default script timeout of ASP.NET, so I was very surprised when the async version was returning a System.TimeoutException, even if it was still taking the same amount of time. I tried increasing the ScriptTimeout, but still no luck: the page was timing out. After a bit of searching online I found out that for some str...
