As a rule, you should always set the DataSource after the DisplayMember and ValueMember. There are often exceptions to rules though, and this is one such exception. If you set the DataSource first and then the DisplayMember and ValueMember, the data is displayed correctly. That goes for Tuples and custom types.
Thanks, that works. I would think that sorting the datasource first would also work, but I haven't tried that. Is there any way to do that with the code you posted in #2?
