    @Gcobani Mkontwana
     
    Please use Concept of ViewBag Instead of that approach:
    Controller:
     
    1. var dtList = from ctry in objContext.Details select ctry; // Source of Country  
    2. foreach (var dt in dtList) {       
    3. countries.Add(dt.Name);   
    4. }   
    5. ViewBag.Names = countries ;   
    6. return View();  
     
    View: 
    @Html.DropDownList("CountryId", new SelectList(ViewBag.Names, "CountryID", "CountryName"))       
     
    OR

    Hi Vishvjit
     
    Ok thanks for the idea, please work with me here for my thought of doing it via the controller to the view within a form. please re-improve if my logic is not correct. 
    1. using using System.Globalization;  
    2.   
    3. using System.Collection;  
    4.   
    5. public actionResult ListCountries(string returnUrl) {  
    6.   
    7. List<string> countries = new List<string>(2);  
    8. var dtList = from ctry in objContext.Details.select ctry;  
    9.   
    10. foreach(var dt in dtList) {  
    11.   
    12. countries.Add(dt.Name);  
    13. }  
    14. return View();  
    15.   
    16.   
    17. // View  
    18.   
    19. ---Assume no reason to inherent model provided i have one created already here  
    20. @model....  
    21.   
    22.   
    23. @{  
    24.   
    25. var CountryItems = new List();  
    26. ..... continues as shown from article.  
    27. }  
    28. @Html.DropDownList("dropDownList", CountrItems)  
    The Question where do i put this logic if i have a form like this,that i want to create?

    Hi,
     
          Better You need to load all  countryId, countriesName and zipcode to the data base. Then retrive and show to the dropdown or chips like what ever you want. The country list db script available some open sources. 
     
    other solution: Load data's in Json locally.
     
    If you want full source code. show some sample of your code.

    If you want to get country name from system check this: 
    https://www.c-sharpcorner.com/uploadfile/dpatra/getting-country-names-from-system/ 
     
     
     OR
    Take Country list from the database or as List of String   
    In Controller:
    List countries =new List(2); 
    var dtList = from ctry in objContext.Details select ctry; // Source of Country
    foreach (var dt in dtList) {     
    countries.Add(dt.Name); 
    } 
    ViewBag.Names = countries ; 
    return View(dtList);
     In View :
    @{ 
    var CountryItems = new List<SelectListItem>();
    CountryItems.Add(new SelectListItem { Text = String.Empty, Value = String.Empty });
     foreach (var name in ViewBag.Names)
    {
     CountryItems.Add(new SelectListItem { Text = name, Value = name }); 
    } 
    }
    @Html.DropDownList("dropDownList", CountryItems)
