I have made an tv-guide where you can see the programs for 5 channels. If you login you can also make an "personal" tvguide. where you can decide which of the 5 channels you are interested in seeing the tableau of, by clicking on their checkboxes. How can I make the application remember the user input. So let's say I log in and open the menu for Channel one (SVT1), and two (SVT2). Then I want these two channels also to be open next time I log in with that user id, how do I do that?

My controller

public class FavoritChannelsController : Controller

{

    TvProgramDBEntities db = new TvProgramDBEntities();



    [Authorize(Roles = "User")]

    public ActionResult channel_index()

    {

        List<Full> model = new List<Full>();

        var list = db.Full.Where(d => d.Date == "2018-11-12").ToList();



        foreach (var item in list)

        {

            if (item.Id <1000)

            {

                var initedF = new Full

                {

                    Channel = Regex.Replace(item.Channel, @"s", ""),

                    Program = item.Program,

                    Time = item.Time,

                    Date = Regex.Replace(item.Date, @"s", "")

                };

                model.Add(initedF);

            }



        }

        return View(model);

    }

}

By using following Command you can Get the UserId of the current user in controllers.

using Microsoft.AspNet.Identity;

.

.

User.Identity.GetUserId()

Use this Id to save/retrieve user choices. For example you can add following entity.

public class User_Channel

{

    public int User_ChannelId { get; set; }

    [MaxLength(128)]

    public string UserId { get; set; }

    public int ChannelId { get; set; }

}
