Question

How would I configure my ViewModel and View to support a dropdown list that contained the following Enum:

public enum PersonType
{
   Bride,
   Groom
}

I would want the text of the dropdown to show “Bride”, “Groom” and the value to be 0 and 1 respectively. I would want to configure a default (either Bride or Groom) for the View as well. The purpose of this is for a “Create” form that I would post and later determine which option was selected (I’m guessing I would need an int within my ViewModel to track what the user selected). How would this get wired up? I’m using Razor.

Answer 1

public enum PersonType
{
   Bride=0,
   Groom=1
}

in your model you will have a property like

public class mymodel{

[Required(ErrorMessage="this field is required")]
public int ID{get;set;}
public IEnumerable<KeyValuePair<string, string>> _list{get;set}
}

in your controller

mymodel model = new mymodel();

model._list=Enum.GetNames(typeof(PersonType))
             .Select(x => new KeyValuePair<string, string>(x, x.ToString()));
return View(model);

and in your view

@Html.DropDownListFor(x=>x.ID,new SelectList(model._list,"key","value"))
@ValidationMessageFor(x=>x.ID)
