I am developping an application with ASP .Net MVC 4 which is french language based, almost of the treatements i have in my app, are based on dates.

For the date textfield i use jQuery DatePicker and i disable hand modifyig fields.

In my Model, i add

[DataType(DataType.Date)]

But when submiting form, the Date Field Is not Validated if the date format is dd/MM/yyyy , but when the date format is MM/dd/yyyy, there is no problems of validation.

I tried to change the locale of my application & used jQuery.Globalize but no solution ! The error message is : The value « 29/04/2014 » is not a valid format for Date d'effet. (The message was displayed in french, but i traduce it for more comprehension).

Could you help me?
