Hello Mark,
You have configured the DropDownList properly - you should omit the name (I can see you have commented it which is okey) or you have to use the same name as the name of the property (in your case City_Id).
The option that I can suggest you to try to change is the ValuePrimite option - it tells the MVVM framework that the field that is going to be updated should be updated with the value of the DropDownList not the whole DataItem.
If this does not help please demonstrate your case with a small demo so we can see why exactly the Customer object is not updated properly inside the Customers_Update action method.
Kind Regards,
