RangeValidator Control

Situations in which a value must fall within a certain range, rather than merely being specified, call for the RangeValidator control. This control allows you to ensure that a specified value is within acceptable limits, using a combination of properties including MaximumValue and MinimumValue. If either of these properties is blank, the control assumes no maximum or minimum (depending on which is blank).

The RangeValidator control allows you to validate the ranges of various data types. You are not restricted to numeric types. In fact, the RangeValidator control supports range validation of any data type described by the ValidationDataType enumeration. These include Currency, Date, Double, Integer, and String.
