Decimal Validation and Binding conflict when french

[Rémi BOURGAREL]

Hi All
I have this model

public class MyViewModel{
[ValidateDecimal]
public decimal ADecimal{get;set;}
}

And this view

$FormHelper.NumberField("myobject.ADecimal")

If myobject.ADecimal is equal to "13.6"

The input will have "13,6" for value (note the comma).
But this value is not passing the Prototype validation.

And if you enter "13.6" in the input the prototype validation is OK
but after the posting myobject.ADecimal is 0 without raising a
validation error on the server side.

Possible Solutions :

- Overriding the prototype number validation so it works with "," (and
every other culture)
- Or forcing the use of "." as separator (ie forcing the culture when
you display the input tag and when you parse the content)

Yes it is, I'm sorry I posted my thread and I didn't finish the title.

Could you step in the code and see whether we are overriding the
conversion code with an InvariantCulture or so? That'd be the only
explanation for the misbehavior..

You don't override it :

 protected static string FormatIfNecessary(object value, IDictionary attributes)
        {
            var formatString = CommonUtils.ObtainEntryAndRemove(attributes, "textformat");

            if (value != null && formatString != null)
            {
                var formattable = value as IFormattable;

                if (formattable != null)
                {
                    value = formattable.ToString(formatString, null);
                }
            }
            else if (value == null)
            {
                value = String.Empty;
            }

            return value.ToString();
        }

the second parameter of toString is "null", so you're using the current UICulture : French so you logically display decimal with a comma, but client side validation will fail :

IsNaN("1,4")

Will return false.

oh well, I dont even remember how we implemented the client side
validation. You should check the js lib used.
