[TypeConverter("Xceed.Validation.Design.ValidationExpressionConverter,Xceed.Validation.v1.3.Design,Version=1.3.20076.12375,Culture=neutral,PublicKeyToken=ba83ff368b7563c6")]

public class DataTypeCriterion : ValidationCriterion

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.
