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.
