Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v25.1.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

    string password
)

VB.NET

Sub SetPassword(
    password As String
)

Parameters

Name	Type	Description
password	String	The password used to write-protect the document.

Remarks

The following example demonstrates how to write-protect a workbook:

C#

using(var workbook = new Workbook())
{
    var wpOptions = workbook.DocumentSettings.WriteProtection;
    wpOptions.SetPassword("Password");
    wpOptions.UserName = "John Smith";
    workbook.SaveDocument("WriteProtectedDocument.xlsx");
}

VB.NET

Using workbook As New Workbook()
    Dim wpOptions As WriteProtectionOptions = workbook.DocumentSettings.WriteProtection
    wpOptions.SetPassword("Password")
    wpOptions.UserName = "John Smith"
    workbook.SaveDocument("WriteProtectedDocument.xlsx")
End Using

When users open this workbook in Microsoft® Excel®, it prompts them to enter a password to modify the document.

Note

Write-protection options are ignored when you open a document in the WinForms or WPF Spreadsheet control. You can handle the SpreadsheetControl.DocumentLoaded event to check whether the document is write-protected (or its ReadOnlyRecommended option is enabled). If true, activate the control’s ReadOnly property.
