} @foreach (var p in Model.Products) { @p.Name @p.Price.ToString("c") @p.Description } @Html.PageLinks(Model.PagingInfo, x => Url.Action("List", new { page = x })) THE PROBLEM WITH STYLING ELEMENTS The HTML elements generated by an MVC application come from a variety of sources (static content, Razor expressions, HTML helper methods, etc.), so the style classes become diffused throughout the project. If this makes you feel slightly uncomfortable, then you are not alone. Mixing the CSS styles in with element generation is not a great idea and runs counter to the idea of separating out unrelated functionality that pervades MVC. You can improve on this situation by assigning non- Bootstrap classes to elements based on their role in the application and then use a library like jQuery or LESS to map between your custom classes and the Bootstrap ones. I am going to keep things simple for this application and accept that I have embedded the Bootstrap classes throughout the application, even though it complicates the process of changing styles in the future. I would not do this in a real project, but I know this example application is not going to enter into a maintenance phase. If you run the application, you will see that I have improved the appearance—at least a little, anyway—as illustrated by Figure 7- 17. 196
Figure 7-17. The design-enhanced SportsStore application Creating a Partial View As a finishing trick for this chapter, I am going to refactor the application to simplify the List.cshtml view. I am going to create a partial view, which is a fragment of content that you can embed into another view, rather like a template. Partial views are contained within their own files and are reusable across multiple views, which can help reduce duplication if you need to render the same kind of data in several places in your application. To add the partial view, right-click the /Views/Shared folder in the SportsStore.WebUI project and select Add View from the pop-up menu. Set View Name to ProductSummary, set Template to Empty, select Product from the Model Class drop-down list and check the Create As A Partial View box, as shown in Figure 7-18. 197
