Question

I create my selectlist from enum.

[Flags]
public enum Age
{
    New_Born = 1,
    Toddler = 2,
    Preschool = 4,
    Kindergarten = 8,
    Elementary_School = 16,
    Middle_School = 32,
    High_School = 64
}


var age = from Age e in Enum.GetValues(typeof(Age))
          select new { Id = (int)e, Name = e.ToString().Replace("_", " ") };

I tried both:

var ageList = new SelectList(age, "Id", "Name", (int)Model.Child.Age);

or

var ageList = new SelectList(age, "Id", "Name", Model.Child.Age);


@Html.DropDownListFor(m => m.Child.Age, ageList, "Your Child's Age")

Everything works except the selected value didn’t get selected.

EDIT: after hours testing, finally fix it.
chagne Id = (int)e to Id = e.

var age = from Age e in Enum.GetValues(typeof(Age))
          select new { Id = e, Name = e.ToString().Replace("_", " ") };

var ageList = new SelectList(age, “Id”, “Name”, Model.Child.Age);
