Related API Members

The following members return ProtectedRange objects:

• ProtectedRangeCollection.Add(String, CellRange)
• ProtectedRangeCollection.Add(String, IList<CellRange>)
• ProtectedRangeCollection.Add(String, String)

Remarks

A simple scenario that uses the ProtectedRange is illustrated in the code snippet below.

The entire worksheet is protected with a “password” password. End-users can only select cells.

On an attempt to edit range “C3:E8” on a protected sheet, the end-user will be prompted for a password (“123”) unless the application which loaded the worksheet is not run under the same account as the application which has executed the following code snippet. If it is so, a password is not required to edit the range “C3:E8”.
