Return Value

Some documents such as PDF can be protected and cannot be read without the user supplying a password. The readers will automatically detect if a document is encrypted, and will call the DocumentReaderGetPasswordCallback delegate set in the DocumentReaderLoadOptions.GetPasswordCallback property. The application can then show a dialog box to prompt the user for the password (or set a fixed value if the password is known in advance).

For an example, refer to DocumentReaderLoadOptions.
