display string message for integer type attributes

Question

User364607740 posted

I have a model class,

namespace myapp.Models
{
    public class SchoolModels
    {
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int Id { get; set; }
        [Required]
        public int ShoolType { get; set; }        
    }
}

In Create.cshtml page, I have created a static drop down list to select the value for ShoolType attribute.

@Html.DropDownList("ShoolType", new List<SelectListItem>
	{
		new SelectListItem {Text = "community", Value = "1"},
		new SelectListItem {Text = "boarding", Value = "2"},
		new SelectListItem {Text = "others", Value = "3"}
	}, "select shool type")

But in Index.cshtml page, I am getting the integer values for ShoolType. How can I display the ShoolType as community for 1, boarding for 2 and others for 3?

public ActionResult Index()
        {
            return View(db.Schools.ToList());
        }

Hi,

You could consider to have a SchoolType entity with an id and a name. This way you'll be able to both know the type name for a given value but you'll be also able to add another school type at any time without any code change.

Another option is to use an enum: https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/enum

scala_1988

{ new SelectListItem {Text = "community", Value = "1"}, new SelectListItem {Text = "boarding", Value = "2"}, new SelectListItem {Text = "others", Value = "3"} }, "select shool type")

@Html.DropDownList("ShoolType", new List<SelectListItem>
	{
		new SelectListItem {Text = "community", Value = "community"},
		new SelectListItem {Text = "boarding", Value = "boarding"},
		new SelectListItem {Text = "others", Value = "others"}
	}, "select shool type")

Try this and change to string. Also, you can create enum to solve this issue

  public enum ShoolType
  {
        Community=1,
        Boarding=2,
        Others=3
   }

namespace myapp.Models
{
    public class SchoolModels
    {
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int Id { get; set; }
        [Required]
        public ShoolType ShoolType { get; set; }        
    }
}

@Html.DropDownList("ShoolType", 
new SelectList(Enum.GetValues(typeof(TestSolution1.UI.Data.ShoolType))), "select shool type")
