The EncryptedFilePasswordCheckFailed event's data class is EncryptedFilePasswordCheckFailedEventArgs. The following properties provide information specific to this event:
|DocumentName||Gets the encrypted document's name.|
|Error||Obtains the password error.|
|Handled||Gets or sets a value that indicates whether the event handler has completely handled the event or whether the system should continue its own processing. Inherited from HandledEventArgs.|

If the TryAgain property is set to true, the Workbook.EncryptedFilePasswordRequest event occurs. The Workbook.InvalidFormatException event fires when the TryAgain property is not specifies or set to false.
