If you want to follow along with this post, at the bottom of the page you can download the project we will create (as always), where you can find attached the SQL script you need to create the database and it’s tables. In Visual Studio 2012 create a new web site, choosing the Empty ASP. Name the site Entity Framework’s approach to create the classes automatically.Rather than talking let’s create a Web Form where we will use a List View control to support CRUD operations for our items.To give you a taste about how our List View will look like, take a look at the following picture which will be the costumized template for displaying Review objects. No Java Script on the Edit Form was causing this nor was the Edit Form tampered with in Share Point Designer 2007.
