Hi Stephen,

The BindingSourceValueMember is the name of the column in the DataTable that is used to update. This is the DataTable that is used to populate the Combobox.

The BindingValueSourceMember is the name of the column in the DataTable you want to update with the contents from the BindingSourceValueMember.

If you look at the sample application that shipped with MMF, the Customer Order form uses comboboxes on the second tab. You can see how Kevin utilizes these properties to make updating to the correct business object much easier than standard databinding.
