Display Default value into dropdown list in mvc4

Question

In MVC4 razor application @Html.DropDownListFor providing selectlist using ViewBag but how to set default value to that drop down is not getting.

 @Html.DropDownListFor(m => m.SlpCode, new SelectList(ViewBag.SalesEmployee1, "Value", "Description"), new { @class = "form-control" })

for that I am tried

@Html.DropDownListFor(m => m.SlpCode, new SelectList(ViewBag.SalesEmployee1, "Value", "Description", (Model.SlpCode==-1)), new { @class = "form-control" })

but still it will not be work. what is another solution for that?

You need to set the value of SlpCode in the controller before you pass the model to the view. If it matches one of the option values (the Value property of SalesEmployee1) then that option will be selected — user3559349

Simply use ViewModel.SlpCode = "DefaultValue" to set DDList default value before returning view in your controller GET method, assume you have a viewmodel. — Tetsuya Yamamoto

this is what i am doing for drop down list

controller code

        public ActionResult Contact()
    {
        Contact homeViewModel = new Contact();
        homeViewModel.subject = new List<Subject>();
        homeViewModel.subject.Add(new Subject { Id = 1, subject1 = "General Customer Service" });
        homeViewModel.subject.Add(new Subject { Id = 2, subject1 = "Suggestions" });
        homeViewModel.subject.Add(new Subject { Id = 3, subject1 = "Product Support" });

        homeViewModel.Selectedid = 1; //this sets the default value for your dropdown

        return View(homeViewModel);
    }

Model code :

public class Contact
 {   [Required(ErrorMessage="Please fill the following")]
    public string name { get; set; }

    [Required(ErrorMessage = "Please Enter Correct Username")]
    [RegularExpression(@"^([0-9a-zA-Z]([\+\-_\.][0-9a-zA-Z]+)*)+@(([0-9a-zA-Z][-\w]*[0-9a-zA-Z]*\.)+[a-zA-Z0-9]{2,3})$", ErrorMessage = "Please provide valid email id")]
    public string email { get; set; }
    public List<Subject> subject { get; set; }
    [Required(ErrorMessage="Please fill the following")]
    public string message { get; set; }
    public int Selectedid { get; set; }
}

View Code :

@Html.DropDownList("Selectedid", new SelectList(Model.subject, "Id",    "subject1", Model.Selectedid), new { @class = "form-control", id = "subject", required = "required" })
