Properties

CanAddSignatureLine

Gets a bool value indicating whether you can add a signature line to a document. Read-only.

bool CanAddSignatureLine { get; }

Property Value

bool

Parent

Returns the Parent object for the specified object.

IWorkbook Parent { get; }

Property Value

IWorkbook

SkipCertificateValidationOnExporting

Indicates whether the validation of the attached digital certificate of the signed signature should be skipped when exporting signed signatures. The default value is true.

If certificate validation is skipped, the certificate will be treated as valid. This is the default behavior.

Otherwise, the certificate will be validated with X.509 chain. The validation requires Internet connection and will read the X.509 certificate storage of the current user and local machine.

bool SkipCertificateValidationOnExporting { get; set; }

Property Value

bool
