I have found that it can bee a lot of different reasont to why this hapend. I have tryed to change my XML file with out sucsess. I hope you will understand what I'm doing wrong.
I will post the parts of my code that i think is relevent Here is my code:
In web.config inside SiteMap-> providers I added this:
<add name="CustomNavigationProvider"
type="BNS.Intranet.HR.CustomPortalNavigation, BNS.Intranet.HR, Version=1.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" NavigationType="Current" />
cs-file
namespace BNS.Intranet.HR
{
public class CustomPortalNavigation : PortalSiteMapProvider
{
public override SiteMapNodeCollection GetChildNodes(System.Web.SiteMapNode node)
{
PortalSiteMapNode pNode = node as PortalSiteMapNode;
if (pNode != null)
{
if (pNode.Type == NodeTypes.Area)
{
SiteMapNodeCollection nodeColl = base.GetChildNodes(pNode);
PortalSiteMapNode childNode = new PortalSiteMapNode(pNode.WebNode, "1", NodeTypes.Area, "http://sp2010dev04/navi/",
"1", "1");
PortalSiteMapNode childNode1 = null;
for (int i = 0; i < 20; i++)
{
childNode1 = new PortalSiteMapNode(childNode.WebNode, "1.1" + i, NodeTypes.Area,
"http://sp2010dev04/navi", "1.1", "1.1");
}
nodeColl.Add(childNode);
SiteMapNodeCollection test = new SiteMapNodeCollection();
if (childNode1 != null)
{
test.Add(childNode1);
childNode.ChildNodes = test;
}
return nodeColl;
}
else // Shouldn't it always return base.GetChildNodes?
return base.GetChildNodes(pNode);
}
else // Only return new SiteMapNodeCollection when pNode is null?
return new SiteMapNodeCollection();
}
