Interesting information.. In the drawback you mentioned about the initial load time. which makes sense, Hhowever, if you are using the same navigation nodes as SharePoint navigation webpart, I assume the initial cost will be beared by the navigation webpart ( or whoever calling it first)

Can you use PSMP for cross web app or cross sites?

"... if you are using the same navigation nodes as SharePoint navigation webpart, I assume the initial cost will be beared by the navigation webpart ..."

That's exactly right. If you use an instance of PSMP which is already supplying the navigation menus, the initial cost will be incurred when rendering the menu for the first time.

With MOSS installed, the nav menus are supplied (by default) by the CombinedNavSiteMapProvider (top) and CurrentNavSiteMapProvider (left) so using one of these two instances to get your items will be slightly faster and will conserve memory. The downside is that these instances HTML-encode the Title property of any node they return. This may or may not be a problem for you depending on your scenario.

"Can you use PSMP for cross web app or cross sites?"

Unfortunately not at this time. The PSMP always draws items from the "context" SPSite.

Do you have any specific code examples on how to extend the navigation provider (PortalSiteMapProvider) in order to customize the navigation? We have two independent navigation blocks horizontal and vertical that requires a different set of links but SharePoint exposes a linear tree of links in its default navigation providers. Or at least this is how I understand it. :)

Thank you,

Vitaly

The PortalSiteMapProvider class is the base provider used by the four default "CMS" SiteMapProviders

This is great information, thanks for spending the time to write this up. I have been working on custom navigation for both top and left nav in MOSS and couldn't figure out how to get the portalsitemapnode from a sitemapnode object... your information said you could cast this so I tried that and it solved my problem. All the information regarding the caching is good to know also, thanks again.

I see your answer about the PSMP not being able to pull in cross collection or cross web application information automatically. But is there a way to programmatically add those nodes to the provider and render out in the navigation object? If so, do you have an example.

I tried running through it with the custom site map provider example in the SDK, but it seems there isn't enough information about what needs to be overridden to accomplish the task of adding in additional nodes.

Thanks.
