MVC 3 AdditionalMetadata Attribute with ViewBag to Render Dynamic UI
Jan 1131A few months ago I blogged about using Model metadata to render a dynamic UI in MVC 2. The scenario in the post was that we might have a view model where the questions are conditionally displayed and therefore a dynamic UI is needed. To recap the previous post, the solution was to use a custom attribute called [QuestionId] in conjunction with an “ApplicableQuestions” collection to identify whether each question should be displayed. This allowed me to have a view model that looked like this: ...

3 things that changed ASP.NET development in 2010
Dec 1023As 2010 draws to a close I thought about how I was writing code last year. I realised how much development has changed in just one year. I want to look at how my work has evolved during 2010.

MVC 2 Model Metadata to Render Dynamic UI
Sep 1009Recently we had a project where we needed to render certain questions on the screen dynamically based on answers to previous questions on previous screens. For questions that need to dynamically be visible/invisible on the same screen, this can simply be controlled with jQuery. However, in this case, based on the user’s input on previous screens we know there are certain questions that will not be applicable before the current screen even loads. In this case, we could use jQuery to set those...
