I have an issue where the selected value is not working for the Html.DropDownList helper method. See below:
This is My Controller:
public ActionResult Ed
change viewbag property name to other then model variable name used on page.
You should change the very name of the field of your DropDownList:
@Html.DropDownList("Some_Name_that_does_not_exist_in_model", ViewBag.NewsItemId as SelectList, string.Empty, new { @class = "form-control" })
