    'Usage
 
Dim instance As DataTypeCriterion
    [TypeConverter("Xceed.Validation.Design.ValidationExpressionConverter,Xceed.Validation.v1.3.Design,Version=1.3.25208.5768,Culture=neutral,PublicKeyToken=ba83ff368b7563c6")]

    Remarks

    The DataTypeCriterion class is the type used for all comparisons. The classes ConstantListCriterion, ConstantValueCriterion, InputValueCriterion, InputCellValueCriterion and RangeCriterion all derive from DataTypeCriterion. Therefore, for criteria based on these types, a data type is specified (and required).

    ValidationDataType.String will be compared using string comparison.

    For the validation of a date, the IFormatProvider is the current thread's date format.
