Remarks

The RestoreDocumentFromStream method is intended to implement caching of 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 CacheReportDocumentEventArgs.SaveDocumentToMemoryStream method. Then, you need to handle the ReportViewer.RestoreReportDocumentFromCache event, and if the document is already stored in cache, restore it via the RestoreDocumentFromStream method.
