How to call more than two models within your View?

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 items = new List();
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 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; }
}
public class CheckBoxViewModel
{
public string None { get; set; }
public string Vegetarian { get; set; }
public string Vegan { get; set; }
public string Halaal { get; set; }
public string Other { get; set; }
}
class="row">
for="Dietary Requirements">Dietary Requirements
class="input-group col-md-offset-3 col-sm-6 col-xs-6">
class="input-group pull-left">
@using(Html.BeginForm("DietOptions", "Home", FormMethod.Post))
{
@Html.CheckBoxFor(m=>m.DietaryModel.Vegetarian, new {@class = "form-control"}) // How make this access those item list? I am struggling here on my View
}

How do you now call this on a View, to get object Count? My issue is on getting the item list on the View side.

Hi For calling more then one moddle in a view you need to create a nested model class.

Eg:
public class ParentModel{
public int Id{get;set;}
public string CountryName{get;set;}
public Childl1 ChildModel1{get;set;}
public Childl2 ChildModel2{get;set;}
}

public class Child1{

public int Id{get;set;}
public string Name{get;set;}
public string Address{get;set;}
}

public class Child2{
public List EmpType{get;set;}
}
Now at ur conroller end call the ParmentModel and pass the values.
Thankjs

Hi Team

What i am trying to achieve inside that form is to get the Count object for looping, if i am trying something like this @for(int i = 0; i
@Html.CheckBoxFor(m=>m.....)
...}

I hope i am trying to make sense to what i am trying to do
