Navigation links from database and QueryString - how?

Hey!
I have table:
- ForumID
- Name
- ParentID
And I want to display navigation links to forums like here:
http://forums.asp.net/15.aspx

Home ? ASP.NET Forums » General ASP.NET » Getting Started


 So I have QueryString - FID with parameter 15 and I'm getting the Names and ID of forums from ParentID

 - ASP.Net Forum - 0
- General ASP.NET - ForumID = 7  - ParentID = 0
- Getting Started - ForumID = 15 - ParentID = 7
