@foreach (string str in Model) {
@str
}
I use a Razor @foreach loop to display the contents of the view model object as items in an HTML list. To demonstrate the
use of this partial view, I updated the /Views/Common/List.cshtml file, as shown in Listing 20-26.
Listing 20-26. Consuming a Strongly Typed Partial View in the List.cshtml File
@{
}
ViewBag.Title = "List";
Layout = null;
This is the /Views/Common/List.cshtml View
@Html.Partial("MyStronglyTypedPartial", new [] {"Apple", "Orange",
"Pear"})
The difference from the previous example is that I pass an additional argument to the Partial helper method which defines
the view model object. You can see the strongly typed partial view in use by starting the application and navigating to the
/Home/List URL, as shown in Figure 20-10.

Using Child Actions
Child actions are action methods invoked from within a view. This lets you avoid repeating controller logic that you want to use in
several places in the application. Child actions are to actions as partial views are to views. You can use a child action whenever
you want to display some data-driven widget that appears on multiple pages and contains data unrelated to the main action that is
running. I used this technique in the SportsStore example to include a data-driven navigation menu on every page, without needing
to supply the navigation data directly from every action method. The navigation data was supplied independently by the child
action.
Creating a Child Action
Any action can be used as a child action. To demonstrate the child action feature, I have added a new action method to the Home
controller, as shown in Listing 20-27.
