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...

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...

Entity Framework 4.3.1 Migrations and non English locale
Apr 1230A few days ago I started migrating a web app I was working on from ASP.NET MVC 3 and EF4 to ASP.NET MVC 4 and EF 4.3.1. All went well, except for some problems with the automatic generation of the DB scheme using EF Code First: it was creating the database, but no tables and not even the __MigrationHistory table added in 4.3; and during the execution of the schema generation an error was raised with a weird datetime conversion error. I tried this both on SQL Express 2005 and SQL Compact and I ...

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...
