WholeNumber	Checks for whole numeric values satisfying given conditions.
Decimal	Checks for decimal values satisfying the given condition.
List	Checks whether a value matches a specified list of values. The maximum length of a list is 255 characters.

The following properties accept/return DataValidationType values:

• DataValidation.ValidationType

Remarks

Use the DataValidationCollection.Add method to create a data validation of the required type. The DataValidation.ValidationType property obtains the type of the data validation. This property is read-only, because the data validation type is specified when the data validation entry is created, and cannot be changed.
