BaseCompareValidator

Synopsis

This abstract class provides basic functionality for the CompareValidator and RangeValidator classes, which perform validation through comparisons. The shared (static) GetFullYear() method converts a two-digit year (like “98”) to a four-digit representation (“1998”), while CutoffYear sets the maximum four-digit year value that it will allow to be represented in two digits. The shared CanConvert() method determines whether a string can be converted to a given ValidationDataType, while the Type property sets the ValidationDataType that the current instance of the control is validating text against.
