ASP.NET.in.a.Nutshell.Second.Edition [Electronic resources] نسخه متنی

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 the validation is performed. Valid data types include integer,
double, date, currency, and string (which uses alphabetic
character-code based comparison). In this way, the
RangeValidator control works identically to the
System.Web.UI.WebControls.RangeValidator control
for full-fledged web pages.

Validation automatically succeeds if the input control is empty. To
require a value, use the RequiredFieldValidator
control in addition to the RangeValidator control
(although it won't render client-side validation
code).
