262 x CHAPTER 7 NAVIGATION they are considered static. The submenus are dynamic, because they appear only when you activate the relevant main menu items. In addition to these properties, the Menu control also has a number of style properties that enable you to change the look and feel of the different parts of the menu. Using the Rendering Mode Earlier versions of the Menu control were criticized because of the HTML they generated. In ASP .NET 2.0 and 3.5, the Menu control generated bloated HTML using tables and inline styles. Besides increasing the size of the page unnecessarily, this also meant that the Menu was much harder to style using your own CSS. Fortunately, this was fixed in ASP.NET 4 with the introduction of the RenderingMode property on the control. By default in new ASP.NET 4 and 4.5 sites, this property ensures the control renders itself as an unordered list using and elements. You can override this behavior by setting the RenderingMode property to Table instead. You see the Menu control and the HTML it generates in the next exercise. Creating a Basic Version of the Menu Control To see how the Menu control operates, you’re best off creating a very basic version first. Once you understand how it works and how it operates under the hood, you can style the menu to your liking so it blends in with the design of the rest of your site. TRY IT OUT Adding a Menu to the Site In this exercise, you see how to add a Menu control to the master page that uses the Web.sitemap file to build up the menu. The Menu is added to the element in the master page and presents the menu items horizontally. Because of this orientation, this Menu is suitable only for the Monochrome theme. Later you add a TreeView to represent the pages in the site, and write some code that shows the Menu for the Monochrome theme and the TreeView for the DarkGrey theme. 1. Open the master page in Markup View and locate the element. Remove the placeholder text Menu Goes Here. 2. From the Navigation category of the Toolbox, drag a Menu and drop it between the tags. Set the CssClass of the Menu control to MainMenu: 3. Switch to Design View. You may notice that the Design View doesn’t look like the final page anymore. That’s because you may have removed the styleSheetTheme attribute from the element in Web.config. You can leave it like this for now. With much of the styling already done, this isn’t so important. You can still see how the content inside the cpMainContent placeholder is
Using the Navigation Controls x 263 going to end up in the browser. If your Design View does look much closer to the final page, open the Web.config file and remove the styleSheetTheme attribute from the element. 4. Click the Menu control’s gray arrow to open its Smart Tasks panel. 5. From the Choose Data Source drop-down list select . In the dialog box that appears, click the Site Map icon. Figure 7-3 shows the Data Source Configuration Wizard. FIGURE 7-3 6. Click OK to close the dialog box. 7. When you return to the page, the Menu control now shows the top-level element, Home (see Figure 7-4). 8. Click the SiteMapDataSource control once and then press F4 to open or activate the Properties Grid. Change the ShowStartingNode property from True to False. Note that as soon as you do this, the FIGURE 7-4 Menu control in the designer is updated and shows all direct child menus under the root element: Home, Reviews, About, and Login. Figure 7-5 shows how your Menu control should look now.
