The options set in the XlsDocumentOptions class will be used when the user saves a document using the DocumentFormat.Xls format.
To change the options used with the XLS format, perform the following steps:
- Use the DocumentWriter.GetOptions method of the DocumentWriter object being used, passing DocumentFormat.Xls to the format parameter. Note the resulting object from the base DocumentOptions class needs to be cast to XlsDocumentOptions.
- Use the various XlsDocumentOptions properties to change the options.
- Use DocumentWriter.SetOptions to set the new options in the engine.
- Now call the DocumentWriter.BeginDocument method (with DocumentFormat.Xls for the format parameter) to create a new document and add the pages.
Currently, the XlsDocumentOptions class contains no extra options.
