Share a Document
- 2 minutes to read
ASPxSpreadsheet allows multiple users to access the same instance of a document at the same time. These situations may occur in the following cases:
- Multiple users open a document from a common shared document folder on the server file system.
- Multiple users open a document from the open document storage with the same DocumentId.
The collaboration feature is convenient for working with a document on multiple devices. For instance, a user can start to work with a document on a desktop and continue on a mobile device. However, we do not recommend that you use ASPxSpreadsheet in multi-user edit mode because users are able to overwrite each other’s changes.
Limitations
- Users do not receive notifications about changes made by other users. You need to update the page to see the changes.
- Users can access a document’s content copied by another user.
- All users share the document’s history of changes. A user can undo the changes made by another user.
- When you explicitly close a document, every user who works with this document receives the “Your session has expired” error on an attempt to refresh the document.
Prevent Document Sharing
Use one of the following techniques to prevent document sharing:
- If documents are opened from the server’s file system, place user documents into different work folders (specified by the WorkDirectory property) for different users.
- If users open the same document from a custom document storage, open a unique copy of the document (specify a unique DocumentId) for each user.
- Open a document as a template.
