Name
RangeValidator
Synopsis
This class represents a validation control that tests to make sure the value of the
input control
(ControlToValidate) is
equal to or between the MinimumValue and MaximumValue. All values
will be converted to the data type specified by CompareValidator.Type before validation is performed. Valid data types include integer, double, date, currency,
and string (which uses an alphabetic character-code based comparison).
Validation automatically succeeds if the input control is empty. To require a value,
use the RequiredFieldValidator control
in addition to the RangeValidator
control.
