I have a ReorderList control that I am trying to get to work.  I populate it by binding to a DataTable.  If I only bind when !isPostBack then when I click the "save" button all the items in the ReorderList disappear.  If I bind on Page_Load every time (postback or not) then when I click the "save" button all the items get reset to default.  How do I save the state of the items in the list back to the database?  I must be doing something wrong, but I can't figure out what.

Thanks for your help!

Just a quick update... this post by Rick Strahl talks about the same problem that I am experiencing:

It would be useful to have it be able to use a "postback" mode instead of "callback", or maybe I'm just missing something still.  How do I keep the client and server in "sync" with the same items list?

Thanks

Rick's post was before our July 31 release.  We made several changes in response to his suggestions that, at least, got his scenario working properly.  The sync issue was a bug in the ReorderList code - the test was just to bind it to a List<string>.
