다른 사이트 모음에서 탐색을 표시합니다

Question

MySite의 다른 사이트 모음에서 상위 링크 탐색을 어떻게 표시 할 수 있습니까? 이제 사용자 정의 코드가있는 사용자 정의 마스터 페이지가 있지만 현재 사이트 메뉴 만 표시됩니다. 우리는 다른 특정 사이트 컬렉션에서 메뉴를 보여주고 싶습니다.

이는 추가 메뉴를 만드는 방법입니다.

<%@ Register TagPrefix="PublishingNavigation" Namespace="Microsoft.SharePoint.Publishing.Navigation" Assembly="Microsoft.SharePoint.Publishing, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

<publishingnavigation:portalsitemapdatasource id="globalmenuSiteMap" runat="server" enableviewstate="false"
                    sitemapprovider="GlobalNavSiteMapProvider" startfromcurrentnode="false" startingnodeoffset="0"
                    showstartingnode="true" trimnoncurrenttypes="Heading" />

<SharePoint:AspMenu ID="TopNavigationMenuV42" runat="server" EnableViewState="false" EncodeTitle="False"
                        DataSourceID="globalmenuSiteMap" AccessKey="<%$Resources:wss,navigation_accesskey%>"
                        UseSimpleRendering="true" UseSeparateCSS="false" Orientation="Horizontal" StaticDisplayLevels="2"
                        MaximumDynamicDisplayLevels="4" SkipLinkText="" CssClass="s4-tn" />

Answer 1

Unless you want to hard code the links or use some custom data source I only know two different ways to do this, the bad and the horrible way.

The horrible way

Set the current SPWeb to the desired SPWeb and then initialize the menu, for example in a UserControl:

using (var site = new SPSite("http://localhost"))
{
  using (var web = site.OpenWeb())
  {
    var request = new HttpRequest("", web.Url, "");
    var sw = new StringWriter();
    var response = new HttpResponse(sw);
    var originalRequest = HttpContext.Current;
    HttpContext.Current = new HttpContext(request, response);
    SPControl.SetContextWeb(HttpContext.Current, web);
    var siteMapDataSource = new PortalSiteMapDataSource 
    {
      SiteMapProvider = "GlobalNavSiteMapProvider"
    };

    var menu = new AspMenu {DataSource = siteMapDataSource};
    menu.DataBind();
    Controls.Add(menu);
    HttpContext.Current = originalRequest;
    SPControl.SetContextWeb(HttpContext.Current, SPContext.Current.Web);
  }
}

The bad way

(and probably not working properly)

Create your own provider which fetches the navigation directly from the SPWeb:

public class CustomSiteMapProvider : PortalSiteMapProvider
{
  private const string SiteUrl = "http://localhost";

  private static IEnumerable<SPNavigationNode> GetNavigationNodes(string url)
  {
    using (var site = new SPSite(SiteUrl))
    {
      using (var web = site.OpenWeb(url))
      {
        return PublishingWeb.GetPublishingWeb(web).Navigation.GlobalNavigationNodes.
          Cast<SPNavigationNode>().ToList();
      }
    }
  }

  public override SiteMapNodeCollection GetChildNodes(SiteMapNode node)
  {
    var navNodes = GetNavigationNodes(node.Url).ToList();
    var navNode = navNodes.FirstOrDefault(n => n.Url == node.Url);
    if (navNode != null) navNodes= navNode.Children.Cast<SPNavigationNode>().ToList();
    var nodes = navNodes.Select(n => 
      new SiteMapNode(this, n.Url, n.Url, n.Title)).ToArray();
    return new SiteMapNodeCollection(nodes);
  }

  protected override SiteMapNode GetRootNodeCore()
  {
    var publishingNodes = GetNavigationNodes("/");
    var node = publishingNodes.FirstOrDefault();
    if (node == null) return null;
    node = node.Parent;
    return new SiteMapNode(this, node.Url, node.Url, node.Title);
  }
}

Use it like this:

var menu = new AspMenu 
{
  DataSource = new SiteMapDataSource
  {
    Provider = new CustomSiteMapProvider()
  }
};
menu.DataBind();
Controls.Add(menu);

Note that you must call site.OpenWeb for every child SPWeb as SPNavigationNode might have 0 .Children.
Also note that it is using Publishing and Portal, but you can also extend from for example SiteMapProvider for provider (must include more methods) and for nodes you can use web.Navigation.GlobalNodes.

Answer 2

So you already have the navigation bar but need to display the links? I had this issue on My Sites before and to solve it I used a sitemap.

I basically defined all my links for the navigation bar in the sitemap and referenced it in the masterpage. Now whenever a new link is added to the regular site I need to update the sitemap for the My Sites.

Hope that helps!
