fileName | String | A String value specifying the PRNX file, to which the document should be saved. |
Remarks
The SaveDocumentToFile 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 public location via the SaveDocumentToFile method. Then, you need to handle the ReportViewer.RestoreReportDocumentFromCache event, and if the document is already stored in cache, restore it via the RestoreReportDocumentFromCacheEventArgs.RestoreDocumentFromFile method.
