ValidationDataType Enumeration

Specifies the validation data types used by the CompareValidator and RangeValidator controls.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public enum ValidationDataType

Member nameDescription
CurrencyA monetary data type. The value is treated as a System.Decimal. However, currency and grouping symbols are still allowed.
DateA date data type. Only numeric dates are allowed. The time portion cannot be specified.
DoubleA double precision floating point number data type. The value is treated as a System.Double.
IntegerA 32-bit signed integer data type. The value is treated as a System.Int32.
StringA string data type. The value is treated as a System.String.

The ValidationDataType enumeration represents the different data types that the CompareValidator and RangeValidator controls can validate. When you specify a data type for validation control and the input control being validated passes validation, the value of the input control can be parsed to the specified data type.
