Please help.
I am having a problem using DocumentNavigator. Here is the code that i am using in my code.

Private Sub RenderMenuBar(ByVal doc As XmlDocument, ByVal output As HtmlTextWriter)
Dim nav As DocumentNavigator = New DocumentNavigator(doc)
End Sub

And i am also referencing using Imports statement. here is that code.

Imports System
Imports System.Web.UI
Imports System.Web.Caching
Imports System.Web.UI.WebControls
Imports System.ComponentModel
Imports System.Xml
Imports System.IO
Imports System.Collections
Imports System.Text
Imports System.Web
Imports System.Xml.Xsl

But, i am getting an error saying "Type 'DocumentNavigator' is not defined". Please help me. Am i doing something wrong. I am new to using xml in .net.

Thanks for your help in advance.
