BI{code} ?

How can migrate this dropdown ? public ActionResult GetItems(string v) { var list = new List<SelectableItem> {}; list.Add(new SelectableItem { Text = "Male", Value = "M", Selected = v == "M" }); list.Add(new SelectableItem { Text = "Female", Value = "F", Selected = v == "F" }); return Json(list); }

• BI{code} ?

  public ActionResult GetItems() { var list = new List<KeyContent> {}; list.Add(new KeyContent ("M", "Male")); list.Add(new KeyContent ("F", "Female")); return Json(list); } and in the view just set the value: usually it's done by setting the viewmodel property in the controller `input.Gender = "M"; return View(input);` or in the view `Html.Awe().Helper().Value("M")`

  • public virtual ActionResult GetItems(IEnumerable<int> v, int calendarid) { v = v ?? new List<int>(); var list = new List<KeyContent> { }; list.AddRange(db.Calendars.Where(c => c.IsDeleted == false && c.Id == calendarid).SingleOrDefault().CourseCards.ToArray().Select(o => new KeyContent { Content = o.Student.Name, Key = o.Student.Id.ToString(), Selected = v.Contains(o.Student.Id) })); var distinctPartecipants = list.GroupBy(s => s.V).Select(s => s.First()); return Json(distinctPartecipants.ToList()); }

  • the requirement is to return a collection of KeyContent and in the view to set the value of the helper, the rest is up to you from seeing your code I would recommend to always transform to KeyContent in the last step ( `.Select( o => new KeyContent..` ) and call `.ToList()` before transforming to `KeyContent`
