asp.net mvc validation must be a number custom error

Question

I am new to asp.net and I have a problem. When the users insert in a editor for a decimal field something other than numbers, they get an error \"Field name\" is not a number. B

Answer 1

A quick and simple hack for Customize RangeValidator ErrorMessage --"'Field name' is not a number"-- is using RegularExpression

[Range(0.5, 1000, ErrorMessage = "Amount should be in range {1} to {2}.")]
[DataType(DataType.Currency)]
[RegularExpression(@"\d", ErrorMessage = "Amount is not valid.")]
public decimal Amount{ get; set; }
