How to: Protect a Worksheet

You can protect a worksheet by locking cells, so that end-users can only perform a specific (restricted) set of actions specified by the WorksheetProtectionPermissions enumeration member.

By default, all cells in a worksheet have the Protection.Locked attribute set to true. When protection is applied to a worksheet, these cells become read-only. Cells with the Protection.Locked attribute set to false are not protected when worksheet protection is applied, so that the end-users can edit or delete their content.

To apply worksheet protection, use the Worksheet.Protect method, as illustrated in the example below. By default, when you pass the WorksheetProtectionPermissions.Default parameter to the Protect method, a protected worksheet is locked so that an end-user can only select cells.

Expanded Unprotect a worksheet

To remove protection, use the Worksheet.Unprotect method.
