Name Type Description
documentId String

The unique identifier of a document.


Office controls (ASPxSpreadsheet and ASPxRichEdit) do not close a document when you open another document or even when you leave a page with the control. The document storage retains the document until it is hibernated and then removed from the memory after a dispose timeout. If the hibernation is disabled, the document remains in the storage until IIS process recycling occurs.

Call the CloseDocument methods to close a document explicitly:


Call the CloseAllDocuments() method to close all open documents.


When you close a document, DocumentManager closes it for all users who work on the document. It can cause NullReferenceException and “Your session has expired” errors. To avoid these errors, close unshared documents only.
