Remarks
This enumeration is referenced by the InteractivityPostBackMode property in ReportViewer.
If you want the ReportViewer control to perform URL redirection on drillthrough actions, use SynchronousOnDrillthrough. URL redirection is not a supported response to asynchronous postbacks. For more information on synchronous and asynchronous postbacks, see Partial-Page Rendering Overview.
