How to load dropdownbox with 2 value?

Question

Hi,

 

In below code I need to get CustomerSurname as well. In the dropdown box I must show customer surname as: "CustomerName" + " " + "CustomerSurname".

 

// GET: APPROVALs/Create
public ActionResult Create()
{
    ViewBag.CUSTID = new SelectList(db.CUSTOMER, "CUSTID", "CustomerName");
    return View();
}

 

I also need the "db.CUSTOMER" must only get a customer list where CustomerActive = False...

 

Any help please,

Kind Regards,
