# ASP.NET RangeValidator Control

Validation Server Controls

## Definition and Usage

The RangeValidator control is used to check that the user enters an input value that falls between two values. It is possible to check ranges within numbers, dates, and characters.

Note: The validation will not fail if the input control is empty. Use the RequiredFieldValidator control to make the field required.

Note: The validation will not fail if the input value cannot be converted to the data type specified. Use the CompareValidator control, with its Operator property set to ValidationCompareOperator.DataTypeCheck, to verify the data type of the input value.

## Properties

- None (the control is not displayed. Used to show the error message only in the ValidationSummary control)
- Static (the control displays an error message if validation fails. Space is reserved on the page for the message even if the input passes validation.
- Dynamic (the control displays an error message if validation fails. Space is not reserved on the page for the message if the input passes validation

## Examples

RangeValidator
Declare one TextBox control, one Button control, and one RangeValidator control in an .aspx file. If validation fails, the text "The date must be between 1/1/2002 and 31/5/2002!" will be displayed in the RangeValidator control.

RangeValidator 2
Declare one TextBox control, one Button control, one Label control, and one RangeValidator control in an .aspx file. The submit() function checks if the page is valid. If it is valid, it returns "The page is valid!" in the Label control. If it is not valid, it returns "The page is not valid!" in the Label control. If validation fails, the text "The value must be from 1 to 100!" will be displayed in the RangeValidator control.
