Question

How can I hide the root node in a SiteMapPath control when the user is on the root node page? For example, my breadcrumb trail on a child page is:

Home > Products > Hammers > Ball Peen

which is fine. But when the user is on the Home page, the SiteMapPath control displays

Home

which is useless clutter. I want to suppress displaying Home (the root node) when the user is on the home page. I have the SiteMapPath control in a master page. Also, I’m handling SiteMapResolve to set the querystrings in the nodes.

I managed to figure this out but it took a while because the problem I was having was somewhat subtle. schou-rode has the right idea and that is what I was doing in Page_Load without success. The reason it wasn’t working is because I was cloning the node in SiteMapResolve and returning the clone. This occurred before Page_Load so SiteMap.CurrentNode referenced the clone and the comparison to SiteMap.RootNode failed.

Here’s the full solution:

protected void Page_Load(object sender, EventArgs e)
{
    SiteMapPath1.Visible = (SiteMap.CurrentNode != SiteMap.RootNode);
}

private SiteMapNode SiteMap_SiteMapResolve(object sender, SiteMapResolveEventArgs e)
{
    if (SiteMap.CurrentNode == null || SiteMap.CurrentNode == SiteMap.RootNode)
    {
        return SiteMap.CurrentNode;
    }
    // clone and set querystring in other nodes...
}
