ASPxSpreadsheet.Open(String, DocumentFormat, Func<Stream>) Method

Opens a document specified by a stream.

Namespace:DevExpress.Web.ASPxSpreadsheet
Assembly:DevExpress.Web.ASPxSpreadsheet.v17.2.dll

Expanded Syntax

Parameters

documentId
Type: String
A string value that uniquely identifies the document to open (the document's DocumentId).
format
Type: DocumentFormat
A DocumentFormat object specifying the document format.
contentAccessorByStream
Type: Func<Stream>
A method delegate to obtain a stream from which to open the document.

Expanded Remarks

This method tries to find the specified document in a list of already opened documents maintained by the DocumentManager. If the document is found, its instance is opened in the Spreadsheet. If the specified document has not been found in the opened documents, a delegate method specified by the contentAccessorByStream parameter is called. It allows you to manually obtain a steam from which to open a document (for instance, to load a document from a database).
