How do I Change culture to allow (i.e.) spanish datetime in MVC POST?

Question

I checked 10 thousand posts already, none of them did the trick about this very simple problem.

On my UI I have a TextBoxFor for a DateTime property (on my model) very standard stuff.

Model

[DataType(DataType.Date)]
public DateTime DateTo { get; set; }

View

        <div class="Label">
            @Html.LabelFor(model => model.DateTo)
        </div>
        <div class="Control">
            @Html.TextBoxFor(model => model.DateTo, "{0:dd/MM/yyyy}", new { @class = "datepicker" })
            @Html.ValidationMessageFor(model => model.DateTo)
        </div>

jQuery / DatePicker

Just in case, this is the code behind datepicker, I think it's pretty standard from jQuery datepicker, note that In the UI I see datepicker working as expected .

$(".datepicker").datepicker({ dateFormat: "dd/mm/yy", changeYear: true, showAnim: 'blind' });

Culture

So what I learned from other posts, you could change culture to achieve this, but didn't work, I overrided OnActionExecuting with this code:

    Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("ES-AR");
    Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo("ES-AR");

I can see in the Inspection window, that the culture is "es-ar", but problem persists.

Problems!

Problem 1: If I wrote something like '01/02/2018', MVC automatic mapping thinks it's 2nd of January... But actually is meant to be 1st of February.

Problem 2: If I wrote something like '31/03/2018', MVC automatic mapping thinks it's a wrong date (like month 30) but actually is meant to be 30th of march.

Even page validator says " The value '31/03/2018' is not valid for DateTo. "

What am I missing here?

Answer 1

oookey, while explaining this, I got the solution (rubber ducked stackoverflow :/ )...

Solution, It works fine if you put this in your config:

<globalization culture="es-AR" uiCulture="es-AR" />

The new problem I see , what if I wan't to change culture realtime to go back to EN-US? (To change thread culture seems to be the solution, but didn't work as I mentioned above)

For now, it solved my problem.
