Passing Data From View back to the HttpPost method in MVC

Alright so i want to pass data from the view back to Post Method in the controller.

The View : 

    @model IEnumerable< MvcMobile.Models.Trips>

<p>Time : @ViewBag.titi</p>
<p>ID :@ViewBag.iid </p>

<p>From : @ViewBag.From</p>
<p>To :@ViewBag.To </p>


Avaibliabe Trips : 
@foreach (var item in Model)
{
    if ( item.Time==ViewBag.titi)
    {
    <p>@item.TripID</p>
}
}

My HttpGet Method in the controller : 

 [HttpGet]
    public ActionResult Book2(MvcMobile.Models.TicketsBooked tik)
    {

        ViewBag.titi = tik.Time;
        ViewBag.iid = tik.TicketID;
        ViewBag.from = tik.From;
        ViewBag.To = tik.To;
        var TripsList = db.Trips.ToList();
        return View(TripsList);



    }

In This case i cant use a dynamic object to pass variable since the model is IEnumerable

i want to pass one or two textBoxes back to the controller, how can i do that ?

an alternative question would be how can i do the same functionality in the view without making the model IEnumberable ?

and thanks alot.

You should read up on using view models. Basically it's best practice to only pass relevant data to the view. So instead on passing a model of IEnumerable you would have a view model with a property of IEnumerable plus the extra properties you want to post back to your controller.

So for example:

public class ViewModel
{
    public IEnumerable<MvcMobile.Models.Trips> Trips { get; set; }
    public string ExtraValue { get; set; }
}

and your view would be:

@foreach(var trip in Model.Trips)
{
     <p>Do stuff</p>
}

@Html.TextBoxFor(m => m.ExtraValue)

Your post method would then accept a ViewModel.

[HttpPost]
public ActionResult Book2(ViewModel viewModel) 
{
}

You can read up more on view models here or by searching Google / SO. There are many, many examples.
