Remarks

The ValidationCompareOperator enumeration represents the comparison operations that can be performed by the CompareValidator control.

Note

Unlike the other operators, DataTypeCheck is a unary operation. Only the data type of the input control being validated is checked. If the ControlToCompare or ValueToCompare properties are set when this operation is used, those values are not checked.
