I have:
[Required(ErrorMessage = "Price is required.")] public decimal price { get; set; }
How can I change default message for invalid price - I would like to change default error message "The value ‘45,8asasa‘ is not valid for Price.".
You cannot change this unforunately. See, http://forums.asp.net/p/1512140/3606268.aspx But using a javascript hack you can change the error message though, Just put this right after form closing tag, <script type="text/javascript"> var vald = window.mvcClientValidationMetadata[0][‘Fields‘]; for (var i = 0; i < vald.length; i++) { for (var j = 0; j < vald[i].ValidationRules.length; j++) { if (vald[i].ValidationRules[j].ErrorMessage.indexOf("must be a number.") > -1) { vald[i].ValidationRules[j].ErrorMessage = vald[i].FieldName +" Error"; } } } </script> At server side you easily change it by playing with ModelState
