Namespace: Microsoft.Reporting.WebForms
Assembly: Microsoft.ReportViewer.WebForms (in microsoft.reportviewer.webforms.dll)

public enum InteractivityPostBackMode
public enum InteractivityPostBackMode
public enum InteractivityPostBackMode

 Member nameDescription
AlwaysAsynchronousAlways perform asynchronous postbacks. 
AlwaysSynchronousAlways perform synchronous postbacks. 
SynchronousOnDrillthroughPerform synchronous postbacks on drillthrough actions, and asynchronous postbacks on other actions. In this mode, both clicking a drillthrough report and clicking the Back to Parent button will cause synchronous postbacks. For more information on drillthrough reports, see Adding Drillthrough Reports in SQL Server Books Online. 

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.
