Thanx for reply Jameel

Actually I have defined Topic property Like
public SelectList Topic
{
get
{
return new SelectList(
new List<SelectListItem> {
new SelectListItem { Value = "1", Text = "Science", Selected = true },
new SelectListItem { Value = "2", Text = "History" },
new SelectListItem { Value = "3", Text = "Physics" }
}
);
}
}
in my model I am having get accessor so I am binding data from model only.

try this

C#

public static class DropDownList<t>
   {
       public static SelectList LoadItems(IList<t> collection, string value, string text)
       {
           return new SelectList(collection, value, text);
       }
   }
Call the method from the controller like Below.
ViewData["Executives"] =
                DropDownList<executives>.LoadItems(
                    objExecutivesDbContext.Executives.ToList(), "ExecutiveId", "ExecutiveName ");
Call the viewData from the View like below
<div class="editor-field">
            @Html.DropDownListFor(model => model.ExecutiveId, (IEnumerable<selectlistitem>) ViewData["Executives"], "--Select--")

Hope this helps
