May 30, 2012 @ 1:53 am

Creating templated text output that's not tied to the HTTP output stream is a frequent requirement in my applications. Rendering confirmation emails, password resets, validations and notifications all generate text through templates that require string or stream output that doesn't get sent to HTTP. Here are some helpers that make it easy to create string output from MVC Views...

ASP.NET MVC Postbacks and HtmlHelper Controls ignoring Model Changes
April 20, 2012 @ 2:19 am

Today I discovered an MVC behavior I hadn't noticed: For HTML helper controls MVC always uses POSTBACK values to display the control value rather than model values when the View is rendering in a POST back. In effect this means that MVC Views can't update the value of controls during a POST back using the standard HTML Helper Controls.

Physical Directories vs. MVC View Paths
April 05, 2012 @ 2:38 pm

Physical directories that map paths that are also mapped by ASP.NET MVC routes can cause some consternation, especially if you're not aware that there's pathing overlap between the two.

July 30, 2009 @ 3:21 am

WebResources are useful when building more complex components. In MVC ASPX Views you can still access the ClientScript object to retrieve ResourceUrls, but outside of the ASPX view there's no easy access to the ResourceUrl. This post describes how grab resource urls in a couple of different ways.

Introducing CodePaste.NET
July 21, 2009 @ 3:28 am

As a learning experience for taking ASP.NET MVC for a spin I recently created a new site that has now gone live: Codepaste.NET which provides a public location to post code snippet and link them from social network sites that have limited input lengths and make code discussions otherwise difficult. The site's a work in process, but I hope it's useful to some of you for sharing and discussing small blocks of code online.
