    • It can be used for data type check.
    • Compare the value entered into a form field against a fixed value.
    • Compare the value of one form field against another.
    Some of the important property of CompareValidator is as follows.
    ValueToCompare: The fixed value against which to compare.
    ControlToCompare: The ID of a control against which to compare.
    Type: The type of value for comparison. Given values are String, Integer, Double, Date,
    and Currency.
    Operator: Given values are DataTypeCheck, Equal, GreaterThan, GreaterThanEqual,
