ASP.NET MVC datetime culture issue when passing value back to controller

Question

How can i tell my controller/model what kind of culture it should expect for parsing a datetime?

I was using some of this post to implement jquery d

I have a updated solution for MVC5 based on the Post of @gdoron. I will share it in case anyone else is looking for this. The class inherits from DefaultModelBinder and has exception handling for invalid dates. It also can handle null values:

public class DateTimeModelBinder : DefaultModelBinder
{
    public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        object result = null;

        var modelName = bindingContext.ModelName;
        var attemptedValue = bindingContext.ValueProvider.GetValue(modelName)?.AttemptedValue;

        // in datetime? binding attemptedValue can be Null
        if (attemptedValue != null && !string.IsNullOrWhiteSpace(attemptedValue))
        {
            try
            {
                var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
                result = DateTime.Parse(value.AttemptedValue, CultureInfo.CurrentCulture);
            }
            catch (FormatException e)
            {
                bindingContext.ModelState.AddModelError(modelName, e);
            }
        }

        return result;
    }
}

And just like the mentioned sample in the Global.Asax write

ModelBinders.Binders.Add(typeof(DateTime), new DateTimeBinder()); ModelBinders.Binders.Add(typeof(DateTime?), new DateTimeBinder());
