Navigation problem - SDK



I'm trying to test the documentation from Episerver SDK 6 by using the navigation MenuList.

However Visual Studio reports a compilation error. Here is the code and then the error

    protected override void OnLoad(System.EventArgs e)
        Menu.PageLink = PageReference.StartPage;
        Menu.PageLoader.GetChildrenCallback = PageReference.StartPage;  // <== Error occurs.. EPiServer.Web.WebControls.HierarchicalPageLoader.GetChildrenMethod' is a  'type', which is not valid in the given context 

    /// Creates the collection for the main menu, adding the startpage
    private PageDataCollection LoadChildren(PageReference pageLink)
        PageDataCollection pages = DataFactory.Instance.GetChildren(pageLink);
        pages.Insert(0, DataFactory.Instance.GetPage(pageLink));
        return pages;

    /// Gets or sets the MenuList for this control
    public MenuList MenuList
        get { return Menu; }
        set { Menu = value; }

Kind regards,

I managed to make it to work by

changing the line to this:

Menu.PageLoader.GetChildrenCallback = new HierarchicalPageLoader.GetChildrenMethod(LoadChildren);

However, I don't understand "LoadChildren". The funciton is supposed to take one parameter (Pagereference),

but exception occur "method name is expeced".

Someone how have a good explanation on this?

It must be an error in the example. The GetChildrenCallback is a delegate expecting a method that conforms to methothname(Pagereferece).

When the pageloader code is run it will use the specified method instead of the builtin.
