Wicked Code: Three Cures for Common Site Map Ailments

摘要

Data-driven site navigation is among the niftiest and most useful features in ASP.NET 2.0. To get it working, all you do is create an XML site map file (or a SQL site map if you're using the MSDN~® Magazine SqlSiteMapProvider), add a SiteMapDataSource, and bind a Tree View or Menu to the SiteMapDataSource. Just like that, you have a data-driven navigation UI. If the structure of your site changes, simply update the site map and the navigation UI changes to match. For good measure, you can throw in a SiteMapPath control to implement a bread crumb element showing the path to the current page.
