How to: Create Protected Ranges in Code

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E3017.

This code snippet illustrates how to unlock specific document ranges in a protected document for authenticated users by doing the following:

  1. Access the document collection of ranges with permissions by calling the SubDocument.BeginUpdateRangePermissions method.
  2. Call the RangePermissionCollection.CreateRangePermission method to create a RangePermission instance to the target document range.
  3. Specify the user and/or the group of users that are eligible to edit the document using the RangePermission.Group and RangePermission.UserName properties.

    In this example, actions from step 2 and 3 are implemented in the CreateRangePermissions method.

  4. Finish the update by calling the SubDocument.EndUpdateRangePermissions method.
  5. Use the Document.Protect method to protect the document from modification. With document protection enabled, ranges without edit permission are read-only.
