As we already know, Razor is maybe the best view engine for ASP.NET MVC so far. It keeps your code fluid and very expressive.

Instead, you should specify @functions { } so that inside the bracke...
There are several view engines you can use with ASP.NET MVC: ASPX Razor Spark NHaml etc… Also, you can create your own View Engine .

In the previous two ( first , second ) blogs I've shown how to use the Data Linking jQuery plugin which was created by Microsoft. In one of the blogs I've shown how you can map the data to some custom named fields in your jQuery object variable. Except linking, you can also unlink the already linked data. How to do that? See the following example: var person = {}; //empty person $("#myFo...
