Introduction


MvcSiteMapProvider is, as the name implies, an ASP.NET MVC SiteMapProvider implementation for the ASP.NET MVC framework. Targeted at ASP.NET MVC 2, it provides sitemap XML functionality and interoperability with the classic ASP.NET sitemap controls, like the SiteMapPath control for rendering breadcrumbs and the Menu control.
Based on areas, controller and action method names rather than hardcoded URL references, sitemap nodes are completely dynamic based on the routing engine used in an application. The dynamic character of ASP.NET MVC is followed in the MvcSiteMapProvider: there are numerous extensibility points that allow you to extend the basic functionality offered.

• Html.MvcSiteMap().Menu() - Can be used to generate a menu
• Html.MvcSiteMap().SubMenu() - Can be used to generate a submenu
• Html.MvcSiteMap().SiteMap() - Can be used to generate a list of all pages in your sitemap
• Html.MvcSiteMap().SiteMapPath() - Can be used to generate a so-called "breadcrumb trail"

      : DynamicNodeProviderBase
    {

        public override IEnumerable GetDynamicNodeCollection()
        {
            // Build value
            var returnValue = new List();

            // Create a node for each Cookie
            foreach (var ck in storeDB.cookies1.Where(x => x.DescriptionStatus.ToUpper() == "MODERATION"))

                returnValue.Add(node);

            // Return
            return returnValue;
        }

        public override CacheDescription GetCacheDescription()
