BindingSource.Current

I am using a binding source with a datagridview and when double clicking on a row in the datagridview, the bindingsource.current does not seem to be updated? I have found a work around, but would rather use the binding source:

Workaround:

Dim record = DirectCast(dgv.SelectedRows.First.DataBoundItem, Scenario)

Original:

Dim record = Direcast(bs.current, Scenario)

Thanks Kirk
