On my previous post Georgio provided a sample app that has a tabstrip bound to a sitemap, registered in global.asax.cs and bound in the sitemaster (see http://www.telerik.com/community/forums/aspnet-mvc/tabstrip/can-you-put-the-tabstrip-in-a-master-page.aspx#1235366). When I moved the code to my project, I added this to the global.asax.cs:
protected void Application_Start()
{
// register the sitemaps into SiteMapManager.SiteMaps collection
SiteMapManager.SiteMaps.Register<XmlSiteMap>("AdminSitemap", sitmap => sitmap.LoadFrom("~/Sitemaps/Admin.sitemap"));
....
and this to my view:
<%
= Html.Telerik()
.TabStrip()
.Name(
"TabStrip")
.BindTo(
"AdminSitemap")
%>
and this to the bottom of my site.master before the end body tag:
<% Html.Telerik().ScriptRegistrar().OnDocumentReady(() =>
{
%>
jQuery('#TabStrip').bind('dataBound', function(){Sys.Mvc.FormContext._Application_Load()})
<%
})
. Render();
%>
When I run this project that looks to me like the sample project, I get:
Server Error in '/' Application.
You must have SiteMap defined with key "AdminSitemap" in ViewData dictionary.
What am I missing? Where does the AdminSitemap get loaded into the viewdata for the home view?
Thanks,
Bill

Unfortunately it is hard to determine what could be the reason for the depicted issue. In order to progress with the investigation of the problem, I will ask you to send us a simple test project which reproduces the described erroneous behavior.
