How to use combobox as record selector within a bindingnavigator?

Hi all,

I'm making a windows forms .net 4 vs2010 app. I've got a bindingnavigator in place for header/lines record navigation.

I noticed that the designer allows you to add controls to the bindingnavigator strip, so I added a combobox. Giving the user random-access ability to select records would be preferable than the sequential access that defaults.

I'm not sure how to sync the bindingnavigator added-on combobox to the bindingsource that the rest of the bindingnavigator uses. Help?

Thanks for any tips,
