String | The document identifier. |
Remarks
A document in the web server’s memory is identified by a unique string – document ID. All operations that you perform in ASPxSpreadsheet affect the active (last opened) document whose document ID value is contained in the DocumentId property.
A new document has an empty document ID value, thus the document is not accessible from the DocumentManager API. The ASPxSpreadsheet retains such a document until the control switches to another document. The ASPxSpreadsheet generates a document ID value for the document when a user saves it to a file system. Alternatively, you can assign a GUID to the DocumentId property explicitly:
If you open a document from a database, you can use data record key values as document identifiers. The ASPxSpreadsheet control does not send document ID values to the client and uses random GUIDs instead.
