ASP.NET MVC – Using Controller.UpdateModel when using a ViewModel

Posted on by Joe in MVC | 31 Comments

When updating a model in MVC it is common to use the Controller.UpdateModel method.  I recently ran into an issue where I was using a custom ViewModel which meant that UpdateModel could not map the updated data back to my model object. The solution to this was a simple one, but not as obvious as it should be due to intellisense not picking up the method’s overloads when the generic type is inferred.

Creating and using snippets in Visual Studio 2008

Posted on by Joe in Visual Studio 2008 | Leave a comment

Visual Studio contains a number of predefined snippets. Snippets are usually available for common code that is used frequently allowing the developer to insert this code quickly without having to retype it every time. I often use the try and if snippets, but you can also create your own custom snippets. Recently I found myself to be endlessly creating a try/catch block where in the catch I was logging an exception using a custom logger class, so I decided to create a custom snippet to do this for me. In this post I’ll explain how to create a basic snippet, how to configure Visual Studio to use the snippet, and how to use it in code.

In this post I talked about how to use the jTemplates plugin for jQuery. Using my final example in the post I thought it would be cool to try and add some ‘edit in place’ functionality to the table.

For this to work I’ve created a Data Access Layer using Linq to XML. My web service then uses this DAL to save and retrieve my data.
