How to bind WebGrid using StoredProcedure..?

public class Registration
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Email { get; set; }
        public string Gender { get; set; }
        public string Address { get; set; }
        public string City { get; set; }
        public string State { get; set; }
        public string Country { get; set; }
        public Int64 PhoneNumber { get; set; }
        public string Password { get; set; }
    }

public DataSet Registration_Select(Registration objRegistration)
{
   return SQL.ExecuteDataset(sqlconn,CommandType.StoredProcedure,
"TR_Registration_Select");
}

BaseAccessLayer:
<pre lang="c#">public DataSet Registration_Select(Registration objRegistration)
{
    return objDL_Registration.Registration_Select(objRegistration);
}

public class GridController : Controller
{
    Registration list = new Registration();
    BL_Registration obj = new BL_Registration();
    public ActionResult Grid()
    {
       List<registration> list = GetRegistration();
       return View(list.AsEnumerable());    
    }

    public List<registration> GetRegistration()
    {
       DataSet ds = obj.Registration_Select(list);
       if (ds.Tables.Count > 0)
         {
            return Grid = ds.Tables[0];
         }
    }
}
