DocumentManager.CloseAllDocuments() Method
Closes all open documents.
Namespace: DevExpress.Web.Office
Assembly: DevExpress.Web.v24.1.dll
NuGet Package: DevExpress.Web
Declaration
Remarks
The CloseAllDocuments method closes all open documents and clears all the session parameters, including the Rich Text Editor/Spreadsheet settings.
Note
The CloseAllDocuments method is not in effect when a custom StateProvider is used.
We recommend that you use the CloseDocument(String) method to close only specific documents specified by the document ID.
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.
