MinLength(min : Integer, message : String)

Applied to: String

The String value must have a length equal to or greater than the specified <i>min</i> value.

MaxLength(max : Integer, message : String)

Applied to: String

The String value must have a length equal to or less than the specified <i>max</i> value.

IsNumber(message : String)

Applied to: String

The String value must represent a decimal number.

Pattern(format : String, message : String)

Applied to: String
