Section Identifier

Hi there,

I have a site with a top menu like

Home | About us | Services | News | Contact

News has 5 pages beneath it, when someone is on one of the lower pages, I'd like to retrieve the name of the top level page name that the user is in, in this case it'd like to get it to return the value 'News' which is the name of the level 1 page name.

What would be the best way to get it?

I can find the current page name with

PageSettings currentPage = CacheHelper.GetCurrentPage();

if(currentPage == null){ return; }
if(currentPage.PageTitle == "")
   lblPageName.Text = currentPage.PageName;
   else
   lblPageName.Text = currentPage.PageTitle;

But havent found a way to get the top level pagename it sites under.

Any help would be great.

Thanks

Tim

Re: Section Identifier

Hi Tim,

There are ways of traversing the siteMap nodes to get the topmost parent and then the parent node has the properties for page name url etc.

While I don't have time to code it up for you, you can look in the SiteMenu.ascx.cs for logic how to get the root site map node, and you can look in /Compoenents/SiteUtils.cs to see some methods where I navigate nodes in helper methods. Like you can get the current page node by calling

SiteUtils.mojoSiteMapNode currentNode = GetCurrentPageSiteMapNode(rootNode);

Then get the parent node with

mojoSiteMapNode topParent = SiteUtils.GetTopLevelParentNode(currentNode);

Hope it helps,

Joe

Re: Section Identifier

Joe thats brilliant, thank you so much.

For anyone else out there looking to display the current page name or the top page name, here is the exact code I used

namespace mojoPortal.Web.Controls
{
   public partial class imageMenu : UserControl
   {
   private SiteMapDataSource pageMapDataSource;
   private string siteMapDataSource = "PageMapDataSource";

protected void Page_Load(object sender, EventArgs e)
{

pageMapDataSource = (SiteMapDataSource)this.Page.Master.FindControl(siteMapDataSource);

mojoPortal.Web.mojoSiteMapNode currentNode = SiteUtils.GetCurrentPageSiteMapNode(pageMapDataSource.Provider.RootNode);

menuTextCurrent.Text = currentNode.Title; // current node

mojoSiteMapNode topParent = SiteUtils.GetTopLevelParentNode(currentNode);

menuTextParent.Text = topParent.Title; // parent node

}
}
}
