Tip My custom view engine locations are still in use, but I have specified the view explicitly in the Index.cshtml file, which means that my layout will be obtained from the /Views/Shared folder, even though shared views are located in the /Views/Common folder. When Razor parses the layout, the RenderSection helper method is replaced with the contents of the section in the view with the specified name. The parts of the view that are not contained with a section are inserted into the layout using the RenderBody helper. You can see the effect of the sections by starting the application, as shown in Figure 20-6. I added some basic CSS styles to help make it clear which sections of the output are from the view and which are from the layout. This result is not pretty, but it neatly demonstrates how you can put regions of content from the view into specific locations in the layout. Figure 20-6. Using sections in a view to locate content in a layout Note A view can define only the sections that are referred to in the layout. The MVC Framework will throw an exception if you attempt to define sections in the view for which there is no corresponding @RenderSection helper call in the layout. Mixing the sections in with the rest of the view is unusual. The convention is to define the sections at either the start or the end of the view, to make it easier to see which regions of content will be treated as sections and which will be captured by the RenderBody helper. Another approach, which I tend to use, is to define the view solely in terms of sections, including one for the body, as shown in Listing 20-18. Listing 20-18. Defining a View in Terms of Razor Sections in the Index.cshtml File @model string[] @{ } ViewBag.Title = "Index"; Layout = "∼/Views/Shared/_Layout.cshtml"; @section Header { @foreach (string str in new [] {"Home", "List", "Edit"}) { @Html.ActionLink(str, str, null, new { style = "margin: 5px" }) } } @section Body { 544
This is a list of fruit names: } @foreach (string name in Model) { @name } @section Footer { This is the footer } I find this makes for clearer views and reduces the chances of extraneous content being captured by RenderBody. To use this approach, I have to replace the call to the RenderBody helper with RenderSection("Body"), as shown in Listing 20-19. Listing 20-19. Using RenderSection(“Body”) in the _Layout.cshtml File div.layout { background-color: lightgray;} div.view { border: thin solid black; margin: 10px 0;} @ViewBag.Title @RenderSection("Header") This is part of the layout @RenderSection("Body") This is part of the layout @RenderSection("Footer") This is part of the layout Testing For Sections 545
