I've got an enum defined as such:
Private Enum AllowedMonthNumbers
    _1
    _2
    _3
    _4
    _5
    _6
    _7
    _8
    _9
    _10
    _11
    _12
End Enum
Then a property validator defined as: 
<TypeConversionValidator(GetType(Int32), MessageTemplate:="Card expiry month must be numeric.", Ruleset:="CreditCard")> _
<EnumConversionValidator(GetType(AllowedMonthNumbers), MessageTemplate:="Card expiry month must be between 1 and 12.", Ruleset:="CreditCard")> _
The validation expects "_#", as when I remove the TypeConversionValidator, it passes with setting the value to "_3" or any other number in the enum.
What I need is for this to only accept b/t 1-12, and simply having numeric values in the enum won't work.
Any tips?
Thanks.
UPDATE
I replaced the EnumConversionValidator with a RangeValidator, and attempting to set the parameter to "1", but received the following error:
<RangeValidator(1, RangeBoundaryType.Inclusive, 12, RangeBoundaryType.Inclusive, MessageTemplate:="..."> 
However that's now giving me the following error:
System.Web.Services.Protocols.SoapException : System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.ArgumentException: Object must be of type Int32.
