Remarks

The SiteNavigationSettings class manages navigation settings that are specific to the PortalSiteMapProvider objects that are stored with the SPSite object for a publishing site. The WebNavigationSettings class provides additional settings that are stored with the SPWeb object. These additional settings expand the navigation model to support switching between a PortalSiteMapProvider (“structured navigation”) and a TaxonomySiteMapProvider (“managed navigation”).

Examples

The following example demonstrates creating a sample term set and then configuring a SharePoint web site to use Taxonomy navigation with the sample term set.

using System;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Taxonomy;
using Microsoft.SharePoint.Publishing.Navigation;

namespace NavigationDemos
{
    public class Class1
    {
        public static readonly Guid NavTermSetId = new Guid("<GUID>");
        public static readonly Guid TaggingTermSetId = new Guid("<GUID>");

        //Creates the sample term set. If it exists, it will be deleted
        public static NavigationTermSet RecreateSampleNavTermSet(TaxonomySession taxonomySession, SPWeb web)
        {
            // Use the first TermStore in the list
            if (taxonomySession.TermStores.Count == 0)
                throw new InvalidOperationException("The Taxonomy Service is offline or missing");

            TermStore termStore = taxonomySession.TermStores[0];

            // Does the TermSet already exist?
            TermSet existingTermSet = termStore.GetTermSet(NavTermSetId);

            if (existingTermSet != null)
            {
                //If the TermSet exists, delete it.
                existingTermSet.Delete();
                termStore.CommitAll();
            }

            // Create a new TermSet
            Group siteCollectionGroup = termStore.GetSiteCollectionGroup(web.Site);
            TermSet termSet = siteCollectionGroup.CreateTermSet("Navigation Demo", NavTermSetId);
            NavigationTermSet navTermSet = NavigationTermSet.GetAsResolvedByWeb(termSet, web,
                StandardNavigationProviderNames.GlobalNavigationTaxonomyProvider);
            navTermSet.IsNavigationTermSet = true;
            navTermSet.TargetUrlForChildTerms.Value = "~site/Pages/Topics/Topic.aspx";
            NavigationTerm term1 = navTermSet.CreateTerm("Term 1", NavigationLinkType.SimpleLink);
            term1.SimpleLinkUrl = "http://www.bing.com/";
            NavigationTerm term2 = navTermSet.CreateTerm("Term 2", NavigationLinkType.FriendlyUrl);
            NavigationTerm term2a = term2.CreateTerm("Term 2 A", NavigationLinkType.FriendlyUrl);
            NavigationTerm term2b = term2.CreateTerm("Term 2 B", NavigationLinkType.FriendlyUrl);
            NavigationTerm term3 = navTermSet.CreateTerm("Term 3", NavigationLinkType.FriendlyUrl);
            termStore.CommitAll();

            return navTermSet;
        }

        //Configures the web site to use Taxonomy navigation with the sample term set.
        public static NavigationTermSet SetUpSampleNavTermSet(TaxonomySession taxonomySession, SPWeb web)
        {
            NavigationTermSet termSet = RecreateSampleNavTermSet(taxonomySession, web);

            // Clear out any old settings
            WebNavigationSettings webNavigationSettings = new WebNavigationSettings(web);
            webNavigationSettings.ResetToDefaults();
            webNavigationSettings.GlobalNavigation.Source = StandardNavigationSource.TaxonomyProvider;
            webNavigationSettings.GlobalNavigation.TermStoreId = termSet.TermStoreId;
            webNavigationSettings.GlobalNavigation.TermSetId = termSet.Id;
            webNavigationSettings.CurrentNavigation.Source = StandardNavigationSource.TaxonomyProvider;
            webNavigationSettings.CurrentNavigation.TermStoreId = termSet.TermStoreId;
            webNavigationSettings.CurrentNavigation.TermSetId = termSet.Id;
            webNavigationSettings.Update(taxonomySession);
            TaxonomyNavigation.FlushSiteFromCache(web.Site);

            return termSet;
        }
    }
}
