controling bindingcontext position using a combobox

[dbuchanan]

Hello,


I want to control a bindingContext postion on my form using a comboBox.
How do I set up the comboBox to do that?

Thank you,
dbuchanan

Additional information...
In addition to having a few controls dataBound to a bindingcontext I
intend to have a dataGrid filteted by the valueMember of the comboBox
(the one above) and that dataGrid be given its own bindingContext. The
second binding context will have a couple of its own controls on the
form positioned by the current record on the form.
