Using enum for dropdown list in ASP.NET MVC Core

Question

I'm trying to create a dropdown list with an enum property in ASP.NET MVC Core using the tag helper in a Razor view:

Here is the model:

public class PersonalMember : Member {     [Required, Display(Name = "First Name")]     public string FirstName { get; set; }      [Required, Display(Name = "Last Name")]     public string LastName { get; set; }      [EnumDataType(typeof(Gender))]     public Gender GenderType { get; set; } }  public enum Gender {     Male = 1,     Female = 2 } 

Here is part of a form in the view:

<div class="form-group">     <label asp-for="GenderType" class="col-md-2 control-label"></label>     <div class="col-md-10">         <select asp-for="GenderType" asp-items="Html.GetEnumSelectList<GenderType>()">             <option selected="selected" value="">Please select</option>         </select>         <span asp-validation-for="GenderType" class="text-danger" />     </div> </div> 

The problem I'm having is that after Html.GetEnumSelectList, GenderType is not recognized and shows up as an error.

Does anyone know how to solve this?

Answer 1

I think you accidentally used GenderType instead of Gender. The correct syntax is

<select asp-for="GenderType" asp-items="Html.GetEnumSelectList<Gender>()">     <option selected="selected" value="">Please select</option> </select>
