Remarks
This method overload is used for validation types DataValidationType.Custom and DataValidationType.List.
For the DataValidationType.Custom type, the criteria is a string which can be recognized as a worksheet formula. Therefore, it must begin with an equal sign and evaluate to either true or false.
Note
An individual worksheet cell can have only one data validation rule associated with it. If subsequent Add method calls affect the same cell, only the data validation rule created in the last call is applied.
