Under .NET 2.0 with Visual Studio 2005, I have a combobox on a form that is getting its data from an Access database. It's set up to display one column from the table and return another column's value when an item is selected. When I look at what's in SelectedValue, it contains two copies of the value from the database row. The row is not duplicated in the table, and it appears to be selecting the correct row. Does anyone have any hints as to what might be going on? I set up the associated dataset using the wizard, in case that matters.
