I use MVC 4 and I have the below model defined and use the same in View.I want to show item in a view and render checkbox for each city. So user can select multiple city for a perticular item. \[code\]public class City{int id{get;set;}string name{get;set;}}public class Item{int id{get;set;}List<City> cities{get;set;}}public class ItemController{public ActionResult Save(Item item){ List<city> selectedCitirs=item.cities; // here null return View();}public ActionResult Get(int id){Item item=Service.GetItem(id);return View(item);}}@model item@foreach(City c in item.cities){@Html.CheckBoxFor(c=>c.name)}\[/code\]\[quote\] In a controller i would like to get the selected cities name and want to store in a DB like city1,city2,city3 format.\[/quote\]But controller not giving item.cities. How to do?
