This SaveDocument method overload allows you to encrypt a workbook with a password, as shown below:

C#

// Add a reference to the DevExpress.Docs.dll assembly.
using DevExpress.Spreadsheet;
// ...

Workbook workbook = new Workbook();
// ...

// Specify encryption settings.
EncryptionSettings encryptionSettings = new EncryptionSettings();
encryptionSettings.Type = DevExpress.Spreadsheet.EncryptionType.Strong;
encryptionSettings.Password = "password";

// Save the document.
workbook.SaveDocument("Document.xlsx", encryptionSettings);

VB.NET

' Add a reference to the DevExpress.Docs.dll assembly.
Imports DevExpress.Spreadsheet
' ...

Dim workbook As New Workbook()
' ...

' Specify encryption settings.
Dim encryptionSettings As New EncryptionSettings()
encryptionSettings.Type = DevExpress.Spreadsheet.EncryptionType.Strong
encryptionSettings.Password = "password"

' Save the document.
workbook.SaveDocument("Document.xlsx", encryptionSettings)

Calculate Formulas Before Save Operation

The default calculation mode for a Workbook is Manual. This mode implies that the Spreadsheet does not calculate formulas before it saves a document. Call the Workbook.Calculate or Workbook.CalculateFull method to calculate all formulas in the workbook.
