DropDownList and SelectListItem Array Item Updates in MVC
May 1216So I ran into an interesting behavior today as I deployed my first MVC 4 app tonight. I have a list form that has a filter drop down that allows selection of categories. This list is static and rarely changes so rather than loading these items from the database each time I load the items once and then cache the actual SelectListItem[] array in a static property. However, when we put the site online tonight we immediately noticed that the drop down list was coming up with pre-set values that...

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 Web API (Part 1)
Feb 1224Earlier this week I blogged about the release of the ASP.NET MVC 4 Beta. ASP.NET MVC 4 is a significant update that brings with it a bunch of great new features and capabilities. One of the improvements I’m most excited about is the support it brings for creating “Web APIs”. Today’s blog post is the first of several I’m going to do that talk about this new functionality. Web APIs The last few years have seen the rise of Web APIs - services exposed over plain HTTP rather than through a more f...

Scott Hanselman's 2011 Ultimate Developer and Power Users Tool List for Windows
Dec 1101Everyone collects utilities, and most folks have a list of a few that they feel are indispensable. Here's mine. Each has a distinct purpose, and I probably touch each at least a few times a week. For me, util means utilitarian and it means don't clutter my tray. If it saves me time, and seamlessly integrates with my life, it's the bomb. Many/most are free some aren't. Those that aren't free are very likely worth your 30-day trial, and perhaps your money. Here are most of the contents of my ...

Repaving your PC: the easier way
Nov 1128It"s been a while since I had to repave my laptop. I have a Windows Home Server (WHS) at home which images my PC almost daily and allows restoring it to a given point in time in less than 30 minutes. Which is awesome! And which is how I usually restore my PC into a stable state. Over the past year some hardware changes have been made of which the most noteworthy is the replacement of the existing hard drive with an SSD. A great addition, and it was easy to restore as well: swap the disks and r...

New Bundling and Minification Support (ASP.NET 4.5 Series)
Nov 1128This is the sixth in a series of blog posts I'm doing on ASP.NET 4.5. The next release of .NET and Visual Studio include a ton of great new features and capabilities. With ASP.NET 4.5 you'll see a bunch of really nice improvements with both Web Forms and MVC - as well as in the core ASP.NET base foundation that both are built upon. Today’s post covers some of the work we are doing to add built-in support for bundling and minification into ASP.NET - which makes it easy to improve the perfor...

Implementing an Authorization Attribute for WCF Web API
Oct 1120If you’re not familiar with WCF Web API, it’s a framework with nice HTTP abstractions used to expose simple HTTP services over the web. It’s focus is targeted at applications that provide HTTP services for various clients such as mobile devices, browsers, desktop applications. In some ways, it’s similar to ASP.NET MVC as it was developed with testability and extensibility in mind. There are some concepts that are similar to ASP.NET MVC, but with a twist. For example, where ASP.NET MVC has fi...

Preventing CSRF With Ajax
Oct 1111A long while ago I wrote about the potential dangers of Cross-site Request Forgery attacks, also known as CSRF or XSRF. These exploits are a form of confused deputy attack. Screen grab from The Police Academy movie.In that post, I covered how ASP.NET MVC includes a set of anti-forgery helpers to help mitigate such exploits. The helpers include an HTML helper meant to be called in the form that renders a hidden input, and an attribute applied to the controller action to protect. These helpers...

Writing an ASP.NET MVC Controller Inspector
Aug 111199.99999% of the time (yes, I measured it), a controller in ASP.NET MVC is a type, and an action is a method — with reflection as the glue that holds it all together. For most folks, that’s the best way to view how ASP.NET MVC works. But some folks like to dig deeper and get their hands dirty a bit by taking a peek under the hood. Doing so reveals that while the reflection based mapping of controllers types and actions to methods is true by default, it can be easily changed to something else...

NuGet Package of the Week #9 - ASP.NET MiniProfiler from StackExchange rocks your world
Jul 1122I LOVE great debugging tools. Anything that makes it easier for me to make a site correct and fast is glorious.

Now the triad is complete with MiniProfiler, my Package of the Week #9. Yes, #9. I'm counting System.Web.Providers as #8, so phooey. ;) Hey, have you implemented the NuGet Action Plan?
