Get Hidden Subsites in current navigation

Hello everybody,

I'm using PortalSiteMapProvider to create my own custom navigation, and my own custom navigation control (without site width limitation, i.e, my navigation tree shows subsites to the nth level).

       _portalSiteMapProvider =

newMicrosoft.SharePoint.Publishing.Navigation.PortalSiteMapProvider();

            _portalSiteMapProvider.IncludePages = Microsoft.SharePoint.Publishing.Navigation.

PortalSiteMapProvider.IncludeOption.PerWeb;

            _portalSiteMapProvider.IncludeSubSites = Microsoft.SharePoint.Publishing.Navigation.

PortalSiteMapProvider.IncludeOption.Always;

            _portalSiteMapProvider.NavigationType = Microsoft.SharePoint.Publishing.Navigation.

PortalNavigationType.Current;

            _portalSiteMapProvider.IncludeAuthoredLinks = true;

            _portalSiteMapProvider.IncludeHeadings = true;

later I'm recursing using

foreach

(PortalSiteMapNodesubSiteMapNodeinportalSiteMapNode.ChildNodes)

...

and get all the nodes for my custom top menu.

Thing is, if I use Microsoft navigation page to hide a subsite (i.e, go to /_layouts/AreaNavigationSettings.aspx, choose a subsite and hide it), I can't see it anymore using my loop.

I want to be able to display hidden subsite in my tree.

Does anyone has an idea how to do it?

also I want to be able to perform hide / show subsite in my custom navigation tree. tried using publishingWeb.IncludeInCurrentNavigation - but when I use false - it causes the subsite to disappear from my custom menu - but also from my custom navigation tree.

Thanks,

Barak
