The ModelState.IsValid check in the code verifies that the data submitted in the form can be used to modify a Movie object. The ASP.NET framework model binder takes the posted form values and creates a Movie object that's passed as the movie parameter. The following listing shows the HttpPost version of the Edit action method. The form data will be posted to the server when the Edit button is clicked. The elements are in an HTML element whose action attribute is set to post to the /Movies/Edit URL. (The menu markup was excluded for clarity.)
The HTML in the page looks like the following example. In the browser, view the source for the page. Run the application and navigate to the /Movies URL. The Html.ValidationMessageFor helper displays any validation messages associated with that property. The Html.EditorFor helper displays an HTML element. The Html.LabelFor helper displays the name of the field ("Title", "ReleaseDate", "Genre", or "Price"). The scaffolded code uses several helper methods to streamline the HTML markup. Notice how the view template has a statement at the top of the file - this specifies that the view expects the model for the view template to be of type Movie. The following example shows the Edit view that was generated: = (Html.BeginForm()) => => => => => => => => => => => => => to List", "Index") When the scaffolding system created the Edit view, it examined the Movie class and created code to render and elements for each property of the class. The HttpGet Edit method takes the movie ID parameter, looks up the movie using the Entity Framework Find method, and returns the selected movie to the Edit view. (We'll refer to action methods that are implicitly assigned the HttpGet attribute as HttpGet methods.) You could apply the HttpGet attribute to the first edit method, but that's not necessary because it's the default.
This attribute specifies that overload of the Edit method can be invoked only for POST requests. Notice the second Edit action method is preceded by the HttpPost attribute. ĭb.Entry(movie).State = EntityState.Modified The two Edit action methods are shown below. For example, the URL also passes the parameter ID of 4 to the Edit action method of the Movies controller. You can also pass action method parameters using a query string. Therefore, ASP.NET translates into a request to the Edit action method of the Movies controller with the parameter ID equal to 4. The Edit link was generated by the Html.ActionLink method in the Views\Movies\Index.cshtml view: "Edit", new. Hold the mouse pointer over an Edit link to see the URL that it links to. Run the application and browse to the Movies controller by appending /Movies to the URL in the address bar of your browser. In this section, you'll examine the generated action methods and views for the movie controller. If you prefer Visual Basic, switch to the Visual Basic version of this tutorial.

This tutorial will teach you the basics of building an ASP.NET MVC Web application using Microsoft Visual Web Developer 2010 Express Service Pack 1, which is a free version of Microsoft Visual Studio. It's more secure, much simpler to follow and demonstrates more features. An updated version of this tutorial is available here that uses ASP.NET MVC 5 and Visual Studio 2013.
