I want to feed the menu control from a database which is set up as
WebPageID, WebPageParent, URL where the WebPage Id is the primary key
and the WebpageParent is the foreign key. The menu will have multiple
nodes.
This example works in the treeview but I would really like to use the
horizontal orientation of the menu control. I understand that I may
lose the populate on command.
Does anyone know how to populate the menu control with multiple nodes
from a database?
Thank you in advance for the help.
