I have an enum of some countries:
public enum Countries
{
USA,
Canada,
Mexico,
}
I then have a property on my model:
[Required]
public string Country { get; set; }
In my view I have:
@Html.DropDownList("Country", Html.GetEnumSelectList(typeof(Countries)) ...)
I would like the value of each option in the generated select to be the name of each item from the Countries enum. By default, the value is a zero-based integer.
The values are zero-based integers because you've asked for an EnumSelectList, which outputs an enum (ie the int values).
Instead, you can get the list of enum names, something like:
@Html.DropDownList("Country", new SelectList(Enum.GetNames(typeof(Countries))) ... )
This worked for me:
public class Country
{
[Key]
public int Id { get; set; }
[Required]
public CountryFrom CountryFrom { get; set; }
[Required]
[StringLength (100, ErrorMessage = "Name has to be less then 100 symbols long")]
public string Region { get; set; }
public virtual ICollection<Wine> Wines { get; set; }
}
public enum CountryFrom
{
France, Germany, Italy, Spain, Portugal, UK, India, Bulgaria, Other
}
Insert this in the view and don't forget to import the
<div class="form-group">
<label asp-for="CountryFrom" class="col-md-2 control-label"></label>
<select asp-for="CountryFrom" asp-items="@Html.GetEnumSelectList<CountryFrom>()" class="form-control"></select>
</div>
I hope it will help.
This will help you to have a dropdown list with data taken from enumeration and displaying the name if each item.
i found an very useful tagHelpers on Github by Sakura Iris. https://github.com/sgjsakura/AspNetCore/blob/master/TagHelperDemo.md
You can simply specify the model property, it inherits the source enum and show the Description from a specific Data Annotation. As plus, you can specify the source of values. That's very easy !.
@model Project
<select asp-enum-for="AccessType" asp-text-source="Description" asp-value-source="Value"></select>
