title: Update links on master page with data from child page
body: <p>I have a menu of report links in my master page. I need to append an ID to the end of each whenever the user changes a value on the child page. What's a good way to accomplish this?</p>
  
  <p>UPDATE: I should have mentioned that the child update is happening inside an UpdatePanel, meaning the master page is not reloaded when the change happens.</p>
