If I create a new aspx page e.g. news.aspx and run it, I get errors regarding referencing a NULL value or something along those lines. What I discovered was that I had to put the "news.aspx" page in my Web.sitemap file for it to work. But it was then listed in the main menu, whn it should just be another low profile page someweher in the web site.

I don't want everybody to be able to see all pages (news.aspx is an exception) and have them listed in the main menu etc or have them listed in the Web.sitemap file. I've found some technotes referring to security roles etc but it seemed over the top for creating a news page (for example)

QUESTIONS:

1. Why does the program need to know if a node in the main menu is an ancestor?

2. What does the parameter OnMenuItemDataBound actually do? I assume it is an instruction to go and execute a procedure or function

3. Do I have to have it with menu controls?

I have deleted the OnMenuItemDataBound parameter and commented out the above function code in the AppMaster code behind and it seems to work. This I guess answers the third question, but I would like confirmation, please.

Thank you
