Enum Extention :

    public static class EnumExtention
    {
        public static Dictionary<int, string> GetEnumData(this Type EnumType)
        {
            Dictionary<int, string> objEnumList = new Dictionary<int, string>();

            if (EnumType != null && EnumType.IsEnum)
            {
                foreach (int intCount in Enum.GetValues(EnumType))
                {
                    objEnumList.Add(intCount, Enum.GetName(EnumType, intCount).ToString().Replace("_", " "));
                }
            }
            return objEnumList;
        }
    }

Get Enum Data :

        private enum enumUserType
        {
            Admin,
            Sales_Department,
            Purchase_Department,
            Guest
        }

        protected void Page_Load(object sender, EventArgs e)
        {
            ddlUserType.DataSource = typeof(enumUserType).GetEnumData();
            
            ddlUserType.DataTextField = "Value";
            ddlUserType.DataValueField = "Key";

            ddlUserType.DataBind();
        }

Output :

<select name="ddlUserType" id="ddlUserType">
    <option value="1">Admin</option>
    <option value="2">Sales Department</option>
    <option value="3">Purchase Department</option>
