Use the Operator property to specify the type of comparison to perform. If you set the Operator property to DataTypeCheck, the TCompareValidator component will ignore the ControlToCompare and ValueToCompare properties and simply indicates whether the value entered into the input component can be converted to the data type specified by the ValueType property.

Note that if the input control is empty, no validation functions are called and validation succeeds. Use a RequiredFieldValidator control to require the user to enter data into the input control.
