Thanks for your reply. Actually I figured out what was wrong but hadn't yet written a followup response. The ListView was part of a panel that was getting attached to the page during the ConfigureResponse method. I had thought the configure response method would be a good entry point to swap panels in a very simple wizard page. I've now figured this and adopted something more similar to what is shown on the wiki.
