Now you can to that, by making an ajax call. Now your states dropdown gets all the items(state names), so when the user selects the state you can get the value of that field{provide an id to @Html.DropdownListFor()}if you are using razor and get the value. On select of the state make an ajax call in your java script passing the state value as parameter and write the linq to get all the cities for the states.
Here the stateId needs to be a foreign key in the cities table. So that your query may go like this:- var cities = context.Cities.Where(c=>c.StatesId==stateId)[stateId is the parameter that is passed in the ajax call]

hope you uderstood.
Thank you
