ViewData.ModelState.IsValid is false because Mvc can't parse value which has separated hundreds and thousands with commas

Question

I have fields of type int?.

On view i use jquery plugin which separate textBox value with commas like this : 3,463,436 = 3463436 - it's must be int value.

But on Form subbmit i get error "The value '3,463,436' is not valid for Maximum Contiguous."

Any advice? Thanks.

You will have to something similar for the thousands separator for the int data type.
