Current date in DatePickerDialog Doubt with sorted when sorting list of integers in the form of strings

There are several options to do what you want, here I will indicate one using ViewData:

Your action that receives the POST should be something like the following:

[HttpPost]
public ActionResult Index(datetime fecha, string referencia)
{
    // Acá va tú código

    ViewData["fecha"] = fecha;
    ViewData["referencia"] = referencia;

    return View();
}

Now you must change the code in your view so that you can use these values, for example in the reference input:

<input type="text" id="referencia" name="referencia" class="form-control pull-right" value='@ViewData["referencia"]' />

You may also need to initialize the ViewData in your GET action:

[HttpGet]
public ActionResult Index()
{
    // Acá va tú código

    ViewData["fecha"] = DateTime.Now;
    ViewData["referencia"] = String.Empty;

    return View();
}
