he Microsoft ASP.NET model-view-controller (MVC) represents an alternative architecture to the standard ASP.NET web form model. This alternative is based on the common MVC software design pattern that separates the layers of your website into user interface (view), data and business logic (model), and input handling (controller). This separation through MVC results in loosely coupled objects that are highly testable, can be developed independently from one another, and offer granular control of your application code. ASP.NET MVC 2 is not meant to replace web forms; it is simply an alternative you can take advantage of based on your specific needs. In fact, you can combine both models in a single website. Lesson 1 provides an introduction to the MVC architecture. This includes a definition of MVC and coverage of the execution life cycle of an ASP.NET MVC application and the project structure of the ASP.NET MVC template. You create a simple ASP.NET MVC application at the completion of this lesson. Lesson 2 digs more deeply into MVC. Here you see how to create custom models, views, and controllers. The lesson also discusses MVC routing, application areas, and other MVC topics.

The most significant aspect of the code in Listing 7-2 is the use of the Page_Load method to test for a postback. If this is a postback, meaning that the user has selected an item from the drop-down list, the label displays the name of the color selected, and the label becomes that color. Setting the label color is a little different from setting the label text, as you can see here: Label1.ForeColor = Label1.ForeColor.FromName( _ DropDownList1.SelectedItem.Value) Unlike in earlier versions of Visual Basic, here the ForeColor property isn t a simple number made up of the red, green, and blue values. Instead, ForeColor is a specific type, System.Drawing.Color. You can t, for example, set ForeColor to 255 to get red. A couple of helper functions are available that allow you to set a color using a color name (as in this example) or from a system color, such as ActiveBorder. You can also use one of the predefined colors in the System.Drawing.Color class, which includes everything from SaddleBrown to BlanchedAlmond. Because we ve set the Value attribute of each of the asp:ListItem tags to a color name, we can pass the Value attribute from the selected item to the FromName method and set the ForeColor property to the returned System.Drawing.Color. Figure 7-2 shows the page that appears after you select Green from the drop-down list. (Notice that there is no submit button on this page.)
