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).
