The form in listing 2.6 is built with our input model, NewCustomerInput, from listing 2.5. Note the special HTML helpers that take a lambda expression B. These helpers will parse the lambda expressions and extract the property name, which will then be used as the value for the form element s name attribute. For example, a call to Html.TextBoxFor(x => x.LastName) would generate <input type="text" name="LastName" />. Before strongly typed helpers, we relied on magic strings, and programmers manually ensured consistency between the input form and the processing logic. With strongly typed helpers, like we use in listing 2.6, ASP.NET MVC 2 handles this coordination for the developer, so renaming a property won t cause our screen to malfunction. We cover these helpers in depth in chapter 3.

As we ve already seen, static attributes are overridden by dynamic model items of the same name, so we have introduced a way to set a default value for a couple of model attributes for all views that can be amended by any Controller. Although this concept can be used in any Spring bean definition file, it s a particularly useful and powerful one in the view layer, where you often have many views that will need common values.

Operand1 < Operand2 Operand1 <= Operand2 Operand1 > Operand2 Operand1 >= Operand2 Operand1 == Operand 2 Operand1 != Operand2

Data Annotations, introduced with the .NET 3.5 SP1 release, are a set of attributes and classes defined in the System.ComponentModel.DataAnnotations assembly

Your ApplicationContext and DispatcherServlet context files are usually written in XML using the Spring Beans DTD file. XmlViewResolver allows you to write a view definition file using the same familiar syntax. By default, this file is named WEB-INF/views.xml, and that s where the resolver will expect to find it unless you configure it to look elsewhere. The equivalent XML definition of the preceding views.properties file is displayed in Listing 7-10. Listing 7-10. WEB-INF/views.xml < xml version="1.0" encoding="UTF-8" > <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <bean id="parent-view" abstract="true" class="org.springframework.web.servlet.view.JstlView"> <property name="attributes"> <props> <prop key="title">FlightDeals.com</prop> <prop key="season">Summer</prop> </props> </property> </bean> <bean id="homepage" parent="parent-view"> <property name="url"

that allow you to decorate your classes with metadata. This metadata describes a set of rules that can be used to determine how a particular object should be validated. The Data Annotation attributes control more than validation. Some are used for the new templating features, as we saw in chapter 3 with the DisplayName and DataType attributes. The attributes that specifically control validation are listed in table 15.1.

ASP.NET MVC 2 includes a set of backing validation classes associated with each attribute that are responsible for performing the actual validation. To demonstrate the validation attributes, let s first look at a screen that might need some validation. Figure 15.1 shows an Edit screen that includes Company Name and Email Address fields. In our application, Company Name is a required field and Email Address is optional. To indicate that the Company Name field is required, we use RequiredAttribute, as shown in listing 15.1.

You can define any number of ViewResolvers in your application depending upon your circumstance. A ViewResolver definition resides in the Dispatcher servlet s configuration file (WEB-INF/servletName-servlet.xml by default) and is picked up by the dispatcher based on its class type. Listing 7-11 shows a snippet of the DispatcherServlet context file defining a ViewResolver. Listing 7-11. Configuring a ViewResolver in the Context File <beans> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> <!-- other beans --> </beans>

viewResolver. This is still common but no longer required as the servlet will find all ViewResolvers by type. If you really want it, you can revert to the old behavior by setting the detectAllViewResolvers property of the DispatcherServlet to false.
