Specifies the validation comparison operators used by the System.Web.UI.WebControls.CompareValidator control.
The System.Web.UI.WebControls.ValidationCompareOperator enumeration represents the comparison operations that can be performed by the System.Web.UI.WebControls.CompareValidator control.
Unlike the other operators, DataTypeCheck is a unary operation. Only the data type of the input control being validated is checked. If the CompareValidator.ControlToCompare or CompareValidator.ValueToCompare properties are set when this operation is used, those values are not checked.
