Mike,

As you found out, programmatically changing the SelectedIndex or the SelectedValue of a Combo does nothing to the underlying bound data. It's unfortunate, but that's the way it currently works. You'll have to change the data programmatically as well.

>I have a VB.NET Winform, and it has certain controls bound to a data table. I have a combobox that is bound to the data table, and I also have a checkbox that, when checked, it moves the index of the combobox to 0 and disables it. It looks like it successfully changes on the form, but when I look at my data table, it does not change successfully.
