在ASP.Net MVC5中为DropdownList附加数据绑定项的替代方法是什么

Question

      @Html.DropDownListFor(m => m.Name,(IEnumerable<SelectListItem>)ViewBag.list,
      new { @style = "width:100%", @class = "form-control" }) 

This can help to set the selected item only at run time. How to add few more items at run time (inside controller )

Answer 1

Simple change the source before assigning it to your ViewBag.

eg:

IEnumerable<SelectListItem> yourSource = //...;
var list = yourSource.ToList();
list.Add(...);
ViewBag.list = list;
