Question

I want to display dates and currency amounts in my users chosen format.
How can I retrive this from the client machine?

Alternatively, is there some other way to format dates/currency correctly?

Thanks

A browser exposes it’s locale: You can retrieve it by using ** Thread.CurrentThread.CurrentUICulture**

read more about this here and here

You can overwrite their Culture with a culture of your chosing (if the select another language from a menu perhaps)

to format the date time, and string read here

Watch out, setting a culture happens very soon in a page cycle, if you set it to late, the resource files will be those of a previous selected Culture.

To set the Culture early in the cycle you can create a basepage (that inherits ViewPage){}

using System.Globalization;
using System.Threading;
using System.Web.Mvc;

namespace NerdDinner.Views
{
    public class NerdDinnerViewPage<T> : ViewPage<T> where T : class
    {
        protected override void InitializeCulture()
        {
            base.InitializeCulture();

            Thread.CurrentThread.CurrentCulture = Thread.CurrentThread.CurrentCulture.Clone() as CultureInfo;

            if (Thread.CurrentThread.CurrentCulture != null)
            {
                Thread.CurrentThread.CurrentCulture.NumberFormat.CurrencyDecimalSeparator = ".";
                Thread.CurrentThread.CurrentCulture.NumberFormat.NumberDecimalSeparator = ".";
            }
        }
    }
}

page

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="NerdDinner.Views.NerdDinnerViewPage<NerdDinner.Models.DinnerFormViewModel>" %>

here is the full example, but I copied the code for easyness: example

another approach is using the global asax which can be found here
