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.

Madan Shekar · Answer

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

Sourav Kumar Das · Answer

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""
