public MemoryStream SaveDocumentToMemoryStream()

Returns

Type	Description
MemoryStream	A MemoryStream object, which contains the saved document as a byte array.

Remarks

The SaveDocumentToMemoryStream method is intended to implement caching a web report.

To accomplish this task, you need to handle the ReportViewer.CacheReportDocument event, and if a report document is already generated, save it to a memory stream via the SaveDocumentToMemoryStream method. Then, you need to handle the ReportViewer.RestoreReportDocumentFromCache event, and if the document is already stored in cache, restore it via the RestoreReportDocumentFromCacheEventArgs.RestoreDocumentFromStream method.
