Bind Pages Facade to a Menu

Posted by Community Admin on 13-Feb-2011 00:00

Is there a sample somewhere on binding pages to a RadMenu as per the sitemap in the backend?

This is what I have

var pages = App.WorkWith()

.Pages()

.ThatArePublished()

.Where(x => x.ShowInNavigation == true &&

x.IsBackend == false &&

x.Ordinal > 0)

.Get();

menu.DataSource = pages.OrderBy(x => x.Ordinal);

menu.DataBind();

But not only do they not come out in the right order, there's subpages in the root...

What am I doing wrong? (I assume this is flattening it out?)

Hello Steve,

You are right, the list you get back is flattened. The fluent API is used to work with data objects but it doesn't guarantee preserving the hierarchy of pages - that is a job for the sitemap. Is there any particular reason you want to use the fluent API in this case? Here's how I bound a RadMenu to the sitemap:

var ds = SiteMap.RootNode.ChildNodes;

this.menu.DataFieldParentID = "Key";

this.menu.DataSource = ds;

this.menu.DataBind();

ShowInNavigation is the problem I'm having, the SiteMap doesn't seem to respect it...

It appears this has not been implemented yet. When working with plain LINQ queries like the code below an error pops up as soon as I add the "where o.ShowInNavigation" statement.

var mgr = PageManager.GetManager();

var nodes = mgr.GetPageNodes();

var q = (from o in nodes

where o.ShowInNavigation

select o);

Hi Rein,

Hi there is a bug in the link parser. To workaround it you should use :

o.ShowInNavigation == true

instead only o.ShowInNavigation.

var mgr = PageManager.GetManager();

var nodes = mgr.GetPageNodes();

var q = (from o in nodes

where o.ShowInNavigation == true

select o).ToList();
