MVC – Dropdown list for Enum values

  • Step 1
    • Add enum to the project
    • Define display text for each item in the enum.
    • public enum EnumFieldType
    {
        [Display(Name="Boolean")]
        BOOLEAN,
        [Display(Name = "Integer")]
        NUMERIC,
        [Display(Name = "Decimal")]
        DECIMAL,
        [Display(Name = "Free text")]
        TEXT,
    }
  • Step 2
    • Add in the view below dropdown list code
    • @Html.DropDownListFor(model => model.FieldType,
      from v in (ManageSurveys.Models.EnumFieldType[])(Enum.GetValues(typeof(ManageSurveys.Models.EnumFieldType)))
      select new SelectListItem() {
      Text = ((System.ComponentModel.DataAnnotations.DisplayAttribute)(typeof(ManageSurveys.Models.EnumFieldType).GetField(v.ToString()).GetCustomAttributes(typeof(System.ComponentModel.DataAnnotations.DisplayAttribute), false).FirstOrDefault())).Name,Value = v.ToString(), })
  • This code will display appropriate text in the dropdown and select the int value of enum for save. Also while in edit it will select previously saved value.
