Remarks

The SaveExportOptionsToFile method is intended to store export options when implementing caching for a web report.

To accomplish this task, you need to handle the ReportViewer.CacheReportDocument event and save export options to a public location via the SaveExportOptionsToFile method. Then, you need to handle the ReportViewer.RestoreReportDocumentFromCache event, and restore export options via the RestoreReportDocumentFromCacheEventArgs.RestoreExportOptionsFromFile method.
