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...

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...

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 ...

Referencing Routes in ASP.NET MVC The Rails Way
May 1130Routing is probably the most confusing aspect of working with ASP.NET MVC. It’s hard to craft a groovy URL - even harder to link properly off to that groovy URL. Rails leans on Ruby’s forgiving and friendly nature to make this a bit more simple - C#4 allows to get close to this as well. With Rails 3 you define a route in your config/routes.rb like this: match "order/receipt/:id" => "orders#receipt", :as => :receipt # receipt_url You can access this route anywhere in your application ...

Conditional Filters in ASP.NET MVC 3
Apr 1125Say you want to apply an action filter to very action except one. How would you go about it? For example, suppose you want to apply an authorization filter to every action except the action that lets the user login. Seems like a pretty good idea, right? Currently, it takes a bit of work to do this. If you add a filter to the GlobalFilters.Filters collection, it applies to every action, which in the previous scenario would mean you already need to be authorized to login. Now that is security ...

Using EntityFramework with ASP.NET MVC 3
Mar 1121A few people have asked about a comment I made on my last post: I might suggest (in this case) creating an ActionFilter and wrapping the Action in a transaction. It’s transparent, it’s fun… and all the kids are doing it. … and it got me thinking. All of the MSDN samples that I’ve seen which talk about using EF or LinqToSql with ASP.NET MVC almost always show the context being created inside an action or being passed in via a repository. This doesn’t have to be the case - in fact it probabl...
