Hi all,

I have a problem in developing a project. A cutsomer needs to get data from a cascadingdropdown control of a website, I'm trying to get the values from it using jquery, but I always receive an exception about the sitemap,

if (SiteMap.CurrentNode.ParentNode.Equals(SiteMap.RootNode))

Do you know why this appens only if I try to load the page ....mypage.aspx/PageMethod ?? If you want I can give you the address to check, I really need this please help if you can.

Thanks 

Line 24:         HtmlGenericControl momUL = (HtmlGenericControl)FindControl("menu2");
Line 25:         SiteMapNodeCollection momCollection;
Line 26:         if (SiteMap.CurrentNode.ParentNode.Equals(SiteMap.RootNode))
Line 27:             momCollection = SiteMap.CurrentNode.ChildNodes;
Line 28:         else
