>The reason I was asking is because when you do an update using the AJAX ToolKit ReOrder list it uses reflection on the DataTable created in the select method to generate the update parameters instead of the parameters specified in the Update method you specify on your SqlDataSource. So your update method has to have all the fields in your select method as parameters. Sounded like you were having a similar issue.
