The BaseCompareValidator class is inherited by validation controls that compare values, such as the CompareValidator and RangeValidator controls, to provide basic common functionality.
Use the Type property to specify the data type that that the values are converted to before being compared.
 Note |
|---|
| If the value of the input control being validated cannot be converted to the specified data type, validation fails. The IsValid property of the validation control is set to false. |
The BaseCompareValidator class also contains several static properties and methods that are useful when performing comparison validations. You can determine whether a string can be converted to a specific data type by using the CanConvert method. The maximum year that can be represented by a two-digit year is contained in the CutoffYear property. The GetFullYear method allows you to convert a two-digit year to a four-digit year.
