Bind dropdownlist from enum in Asp.Net

In this post we will discuss how to bind a dropdownlist from enum in asp.net. Also you can check my previous posts on:

Here is an example where I am binding a dropdownlist from a enum.

First write an enum like below:

 public enum UserRole

    {

        Developer = 1,

        Admin = 2,

        SuperAdmin = 3,

        SuperDuperAdmin = 4

    }

Now we can put a dropdownlist in the .aspx page and we can bind like below:

Below is the full code:

.Aspx Code:

<div>

      User Roles:  <asp:DropDownList ID="ddlUserRoles" runat="server"></asp:DropDownList>

</div>

.CS Code:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

public partial class EnumTest : System.Web.UI.Page

{

    public enum UserRole

    {

        Developer = 1,

        Admin = 2,

        SuperAdmin = 3,

        SuperDuperAdmin = 4

    }

    protected void Page_Load(object sender, EventArgs e)

    {

        if (!IsPostBack)

        {

            string[] enumRoles = Enum.GetNames(typeof(UserRole));

            foreach (string item in enumRoles)

            {

                //get the enum item value

                int value = (int)Enum.Parse(typeof(UserRole), item);

                ListItem listItem = new ListItem(item, value.ToString());

                ddlUserRoles.Items.Add(listItem);

            }

        }

    }

}

After this it will come like below:
