Html.DropDownListFor value not selected on edit mode

I am succesfullly able to save value to database (title value) on insert , but when i render the same view in edit mode then title field must hold the selected value but in my case no value is selected by title dropdown...dont know why i am getting a dropdown with nothing selected while title field holds the stored value(at backend).

@Html.DropDownListFor(model => model.title, new SelectList(Model.titles, "Value", "Text"),"-Select-") // nothing selected on edit mode

 @Model.title //displaying the stored value which the user selected initially.


values for title

titles = new SelectList(ListItem.getValues().ToList(), "Value", "Text").ToList();

getValue function

 public static List<TextValue> getValues()
      {
    List<TextValue> titles= new List<TextValue>();
    TextValue T= new TextValue();


   T.Value = "Mr";
   T.Text = "Mr";
   titles.Add(T);

    T= new TextValue();
    T.Value = "Mrs";
    T.Text ="Mrs";
       titles.Add(T);

     T= new TextValue();
   T.Value = "Miss";
   T.Text = "Miss";
    titles.Add(T);

    T= new TextValue();
    T.Value ="Other";
   T.Text = "Other";
   titles.Add(T);


    return titles;

   }

You've got to use another ctor of SelectList

From msdn

SelectList(IEnumerable, String, String, Object)

Initializes a new instance of the SelectList class by using the specified items for the list, the data value field, the data text field, and a selected value.

Then :

@Html.DropDownListFor(model => model.title, 
                      new SelectList(Model.titles, "Value", "Text", Model.title),
                      "-Select-")

By the way, it's generally a good idea to follow basics standards (at least) : your properties should begin by an Upper case char.

public string Title {get;set;}

Controllers:

    Model.titles = new SelectList(ListItem.getValues(), "Value", "Text");

    public static List<SelectListItem> getValues()
    {
        List<SelectListItem> titles= new List<SelectListItem>();
        SelectListItem T= new SelectListItem();

        T.Value = "Mr";
        T.Text = "Mr";
        titles.Add(T);

        T = new SelectListItem();
        T.Value = "Mrs";
        T.Text = "Mrs";
        titles.Add(T);

        T = new SelectListItem();
        T.Value = "Miss";
        T.Text = "Miss";
        titles.Add(T);

        T = new SelectListItem();
        T.Value = "Other";
        T.Text = "Other";
        titles.Add(T);

        return titles;
    }

    public ActionResult Edit(int sno)
    {
        var model = db.table.SingleOrDefault(x => x.sno == sno);
        return View(model);
    }
