Doesn't your siggy indicate you have a bias or are one of those anti-Anything-Made-By-Microsoft people?

You don't do databinding like this using a DataReader. A DataReader reads through the returned records forward only. Since during the first bind, you had the reader go through all the records once, there's no way to get it to go back and do it again for the second bind. Drop the DataReader and use a DataAdapter to fill a DataTable, then you can bind both ComboBox's (please don't use abbreviations like DDL!) to that DataTable.
