Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v24.2.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

void Protect(
    string password,
    WorksheetProtectionPermissions permissions
)

Parameters

Name Type Description
password String

A string that specifies a password for the worksheet. If the password is an empty string, the worksheet can be unprotected without using a password.

permissions WorksheetProtectionPermissions

Remarks

If the worksheet is already protected, the Protect method throws an exception. Check the Worksheet.IsProtected property before calling the method.

View Example

Worksheet worksheet = workbook.Worksheets["ProtectionSample"];
workbook.Worksheets.ActiveWorksheet = worksheet;

// Protect the worksheet. Prevent end-users from changing worksheet elements.
if (!worksheet.IsProtected)
    worksheet.Protect("password", WorksheetProtectionPermissions.Default);
// Add a note.
worksheet["B2"].Value = "Worksheet is protected with a password. \n You cannot edit or format cells until protection is removed." +
                        "\nTo remove protection, on the Review tab, in the Changes group," +
                        "\nclick \"Unprotect Sheet\" and enter \"password\".";
worksheet.Visible = true;

You can selectively unlock ranges in a protected worksheet. To do this, add a ProtectedRange to the Worksheet.ProtectedRanges collection. You can specify a password to edit the protected range with the ProtectedRange.SetPassword method and give specific users permission to edit the range with the ProtectedRange.CreateSecurityDescriptor method.
