I have a combo box bound to a control binding manager which is bound to a data source.  It works fine.  The user selects a name from the drop down list and it saves and retrieves okay.  Now the user wants to change their mind and not have a selection at all.  Without having to put a none in all the tables that I have combo boxes linked to how can I let the user blank out a combo box selection bound to a binding manager?

You don't have to modify your tables.

Just add a Null Entity to the choices in your ComboBox.  You can even give this choice a unique name (e,g, "No one").  For an example of how to do this see the Intermediate tutorial on "Working with ComboBoxes".
