I have my ViewBag for list as ViewBag.TitleList = new SelectList((new string[] { "Mr", "Miss", "Ms", "Mrs" }), contact.Title); //contact.Title has selected value. then I tried converting the array to SelectListItem ( to no avail) On the View it looks like @Html.DropDownListFor(model => model.Title, ViewBag.TitleList as SelectList, "Select") also I tried @Html.DropDownList("Title", ViewBag.TitleList as SelectList, "Select") The list loads successfully but the Selected Value is Not selected . How to Fix this problem? Update The culprit was ViewBag.Title matching my model.Title.
