This is not a question, but rather a response to those who seem to think I have the answer to this problem because there's a question from me in the ASP archives from February, 2003. I would add this response to the original thread, but there appears to be no way to respond to archived posts.

In my instance, the problem was caused by a failure to bind on postback. The binding logic was embedded in an IsPostBack If and was not being executed on subsequent pages. This is the only solution I have to offer.
