Hi Team

 

I have two models within a view and have created a checkbox, inside i cant seem to call all of my item list. Who can help with this logic below of mine? What i want here to get all lists of my items from table column within database.

 

  public ActionResult DietOptions()
       {
           List<SelectListItem> items = new List<SelectListItem>();
           string constr = ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;
           using(SqlConnection con = new SqlConnection(constr))
           {
               string query = "SELECT Vegetarian, None FROM Dietary";
               using(SqlCommand cmd = new SqlCommand(query))
               {
                   cmd.Connection = con;
                   con.Open();
                   using(SqlDataReader sdr = cmd.ExecuteReader())
                   {
                       while(sdr.Read())
                       {
                           items.Add(new SelectListItem
                           {
                               Text = sdr["Vegetarian"].ToString(),
                               Value = sdr["None"].ToString()
                           });

                       }
                   }
                   con.Close();
               }
           }
           return View(items);
       }


       //POST:/Home/DietaryListOptions.
       [HttpPost]
       public ActionResult DietOptions(List<SelectListItem> items)
       {
           ViewBag.Message = "Selected Items:\\n";
           foreach(SelectListItem item in items)
           {
               if(item.Selected)
               {
                   ViewBag.Message += string.Format("{0}\\n", item.Text);
               }
           }
           return View(items);
       }

 public class RoleViewModel
   {
       public string UserId { get; set; }
       public string Username { get; set; }
       public string Useremail { get; set; }
       public string RoleId { get; set; }

       public EditTrainingRegFormViewModel HomeMainModel { get; set; }

       public CheckBoxViewModel DietaryModel { get; set; }
