Question

When I have a DropDownList that relevant to Model of view like this:

@Html.DropDownListFor(model => model.Group.Name, selectList)

I Can retrieve Values in controller as follow:

string SelectedGroupName = collection.GetValue("Group.Name").AttemptedValue;

But now I have a DropDownList that not relevant to model but I need the value of that, this is my new DropDown:

@Html.DropDownList("DDName", selectList)

How can I retrieve the selected value of that in controller? is there any hiddenfield or other thing to pass value from view to controller?

Edit

This is my view:

@model PhoneBook.Models.Numbers
@{
ViewBag.Title = "Delete";
}
<h2>
    Move And Delete</h2>
<fieldset>
    <legend>Label of Numbers</legend>
<div class="display-label">
        Delete Label And Move All Numbers with: @Html.DisplayFor(model =>
 model.Title)</div>
    <div class="display-field">
        To @Html.DropDownList("DDName", selectlist)
    </div>
</fieldset>
@using (Html.BeginForm()) {
    <p>
    <input type="submit" value="Move Numbers And Delete Label" name="MDbtn" />
     </p>
 }

This is my Controller:

[HttpPost]
    public ActionResult Delete(int id, FormCollection collection) {
var result = Request["DDName"];

//Use result

return RedirectToAction("Index");
}

but result set to null, why?

I think this must be work:

[HttpPost]
  public ActionResult Delete(int id, FormCollection collection)
    {
        var dd = collection.GetValue("DDName");
            .....
    }
