Thanks Jimmy, for the idea,

I wrote the code like the code below and it works, but when I clicked the dropdownlist it only show for Id (sectorid) not the Text (sectorname)

@Html.DropDownList("sectorid", new SelectList((System.Collections.IEnumerable)ViewData["DBSector"]), "sectorid", "sectorname")

How to display Text (sectorname) ?
