XML

Try below code it works for me by using ViewData ...

Step1: Create class for dropdownlist values
public class Country
{
  public int Id { get; set;}
  public string Text { get; set; }
}

 Step2:; Add following code in Controller
 Controller Code:
 public ActionResult Edit(int id)
 {
  var countryList = new[]
  {
   new Roles{ Text = "India", Id= "1" },
   new Roles{ Text = "USA", Id = "2" },
   new Roles{ Text = "UK", Id = "3"},
   new Roles{ Text = "China", Id = "4"},
   new Roles{ Text = "Japan", Id = "5"},
   new Roles{ Text = "Russia", Id = "6"}
  };
  // Passing selected value to dropdownlist(fetch from database or some where else)...
  // For example your class name is customer, dropdownlist display value will be customer.Country in edit mode
 ViewData["countryList "] = new SelectList(countryList, "Id","Text",customer.Country);
 return View(customer);
}

Step3: Add following code in View
View Code:
@Html.DropDownList("countrtddList", ViewData["countryList"] as SelectList)

It appears that the DropDown must not have the same name has the ViewData name.
Happy coding.....

As i understand you, you are saying on your edit page you have a select list, and you want to preselect one of the items.

One of my edit views has a dropdown list of departments. here is what is in my controller:

ViewBag.DepartmentID = new SelectList(db.Departments, "DepartmentID", "DepartmentName", review.DepartmentID);

review.DepartmentID tells the dropdown list to select that item.

Then in the view:

@Html.DropDownList("DepartmentID", String.Empty)

I hope that helps

Can someone please help? I have a similar situation:
I have the following which populates the DropDownList for each row in the model yet does not set the selected value (tblcusts.typeid) in the DropDownList when the page is populated. Any assistance would be greatly appreciated.

Models

public class tblcusts
{
[Key]
public int custid { get; set; }
public int typeid { get; set; }
}

public class tblcusttypes
{
[Key]
public int typeid { get; set; }
public string name { get; set; }
public bool active { get; set; }
}

View

@model IList<mvcapplication1.models.tblcusts>
@for (var i = 0; i < Model.Count; ++i)
{
@Html.DropDownList("typeid", (IEnumerable<selectlistitem>)ViewBag.customertype)

}

Controller

var result = from m1 in db.custs select m1;

var query = from m2 in db.custtypes where m2.active == true orderby m2.name select m2.name;
var CustomerTypeList = new List<string>();
CustomerTypeList.AddRange(query.Distinct());
ViewBag.customertype = new SelectList(CustomerTypeList);

return View(result.ToList());
