Hii Jhon This is why we use viewmodels, it seems like you are a beginner and want to learn the concept, so here i give you sample code to bind dropdown and checkbox in a single view. public class MyViewModel { public List emplist { get ; set ; } // for dropdown public List Checkboxs{ get ; set ;} // for checkboxes } public class Employee_list { public int Empid { get ; set ; } public string EmpName { get ; set ; } } public class CheckboxList_model { public string Text { get ; set ; } public int Value { get ; set ; } public Boolean Selected { get ; set ; } } public List GetEmployeeList() { var connection = GetConnection().GetSection( "ConnectionStrings" ).GetSection( "DefaultConnection" ).Value; SqlConnection con = new SqlConnection(connection); SqlCommand cmd = new SqlCommand( "Select * From Employees" , con); con.Open(); SqlDataReader idr = cmd.ExecuteReader(); List Employees = new List (); if (idr.HasRows) { while (idr.Read()) { Employees.Add( new Employee_list { Empid = Convert.ToInt32(idr[ "EmpoyeeId" ]), EmpName = Convert.ToString(idr[ "EmpName" ]), }); } } con.Close(); return Employees; } } [NonAction] public List ChkMRole() { // here you could get data from database List chkRole = new List (){ new CheckboxList_model{ Text= "Admin" , Value = 1 ,Selected= false }, new CheckboxList_model{ Text= "Vice-Admin" , Value = 2 ,Selected= false }, new CheckboxList_model{ Text= "Member" , Value = 3 ,Selected= false } }; return chkRole; } public IActionResult Index() { MyViewModel vm= new MyViewModel(); vm. Checkboxs=ChkMRole(); vm.emplist =GetEmployeeList(); return View(vm); } // view @model ProjectName.Models.MyViewModel @Html.DropDownListFor(model => model.emplist, new SelectList(Model.emplist, "Empid" , "EmpName" ) , new { @ class = "form-control" }) class = "text-center" > @ for ( int i = 0; i { @Html.CheckBoxFor(m => m.Checkboxs[i].Selected, new { @ class = "" }) @Html.DisplayFor(m => m.Checkboxs[i].Text) @Html.HiddenFor(m => m.Checkboxs[1].Value) }

Hi Jon, You must be passing data to View through ViewModel you can create 2 list inside ViewModel. Then Create an instance and pass data to View. public class MyViewModel{ public List string > List1{ get ; set ;} public List string > List2{ get ; set ;} } To Call it in View public ActionResult MyMethod(){ MyViewModel vm = new MyViewModel(); vm.List1 = .. //Data Filling Logic vm.List2 = .. //Data Filling Logic return View(vm); } Else, You can pass data to View using ViewData or ViewBag public ActionResult MyMethod(){ ViewData[ 'List1' ] = .. //Data Filling logic ViewData[ 'List2' ] = .. //Data Filling logic return View(); } public ActionResult MyMethod(){ ViewBag.List1 = .. //Data Filling logic ViewBag.List2 = .. //Data Filling logic return View(); } View Code: @Html.DropDownList( "MyList" , new SelectList(Model.List1)) // Model.List1/ViewBag.List1/ViewData['List1'] @foreach ( var item in Model.List2) // Model.List2/ViewBag.List2/ViewData['List2'] { @Html.CheckBox(item, false ) @( " " +item) }

Okay you can bind data list in viewmodel in that list ...and then return it view you can see my this article this is of checkbox list add and edit example https://www.c-sharpcorner.com/article/multi-select-checkbox-dropdown-list-create-edit-in-net-core-3-1/

I think you can add both type lists as IDs array in Viewmodel and then bind those list to view with drodown and checkbox..so from this you can get both drop-down and checkbox list ids to your post method on controller.
