Remarks

When you bind the Web Document Viewer or Report Designer to a report specified by name (a string identifier), the control uses custom services, registered in the application, to resolve a report name to a report object. The services are queried in the following order:

1. IWebDocumentViewerReportResolver (Web Document Viewer only)
2. IReportProvider
3. ReportStorageWebExtension

When you save a report in the Web Report Designer, the ReportStorageWebExtension service is called to save the report data.

Create the ReportStorageWebExtension class descendant and register it in your application to implement a custom report storage.
