L' ValidationDataType enumerazione rappresenta i diversi tipi di dati che CompareValidator i RangeValidator controlli e possono convalidare.The ValidationDataType enumeration represents the different data types that the CompareValidator and RangeValidator controls can validate. Quando si specifica un tipo di dati per il controllo di convalida e il controllo di input da convalidare passa la convalida, il valore del controllo di input può essere analizzato nel tipo di dati specificato.When you specify a data type for validation control and the input control being validated passes validation, the value of the input control can be parsed to the specified data type.
