Hi Madan,

This is the sample code,
public List ShowX(int KPI_Id)
        {
            List AppData = new List();

            CommonViewModel model = new CommonViewModel();
            model.AddVM = new ModelA();
            model.SubmitVM = new ModelB();
            DataSet ds = new DataSet();
            string sQuery = "Some query... ";


            SqlCommand cmd = new SqlCommand(sQuery, con);
            con.Open();
            SqlDataAdapter da = new SqlDataAdapter(cmd);
            da.Fill(ds);
            con.Close();
            calculateTotalratings();
            if (ds.Tables[0].Rows.Count > 0)
            {
                foreach (DataRow dr in ds.Tables[0].Rows)
                {
                    AppData.Add(new CommonViewModel()
                    {
                        model.AddVM.KPI_Id = int.Parse(dr[0].ToString()),
                        model.AddVM.Rols_and_Resp = dr[1].ToString(),
                        model.AddVM.Weightage = int.Parse(dr[2].ToString()),
                        model.AddVM.SelfRating = int.Parse(dr[3].ToString()),
                        model.AddVM.SelfRatingComments = dr[4].ToString()
                    });
                }
            }
      }
This is the above sample code....
And i get the error is at line of 23 to 29...where it says ...
"Cannot initialize type"CommonViewModel" with a collection initializer because it does not implement "System.Collection.IEnumerable""

Hi Madan, Bikash,

I have done it but it throws an error....
Madan Shekar7y ago
your controller please do

A objecta=new A();
B objectb=new B();

UnionModel returnobj=new UnionModel();

objecta.name="Madan";
objectb.salary=10;

returnobj.aclassobj=objecta;
returnobj.bclassobj=objectb;

return View(returnobj);

IN VIEW

@model namespace.UnionModel ;

@model.aclassobj.Name

hi sourav,

Madan's replay is right. you just need to create object of model in controller in order to access data whether it is a UnionModel or not.

for example, if you want to access data of Model A than create a object of Model A ,similarly to UnionModel also.

Hi Madan,

I have implemented the models in Model class...

but I need to access those models in the controllers side...

if there's a solution please let me know it...
Madan Shekar7y ago
public class A
{
public string name {get;set;}
}
public class B

{
public string salary{get;set;}
}
public class UnionModel
{
public A aclassobj { get; set; }
public B bclassobj{get;set;}
}

Create object to UnionModel and set the values and return
