ReportViewerControl Session Timeout

[AG]

I am using a ReportViewer Control in an ASP.NET 2.0 web application project
on a shared web host.
It is working fine, except in the case of a session timeout.

ProcessingMode="Remote"
Passing credentials via the method found here:
http://forums.asp.net/t/986174.aspx

If the user remains on the report page and is inactive beyond the session
timeout period. The following exception occurs when they try to return.

Exception Message: ASP.NET session has expired
StackTrace: at Microsoft.Reporting.WebForms.ReportDataOperation..ctor()
at Microsoft.Reporting.WebForms.HttpHandler.GetHandler()
at Microsoft.Reporting.WebForms.HttpHandler.ProcessRequest(HttpContext
context)
at
System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean&
completedSynchronously)
InnerException:
CurrentExecutionFilePath: /Reserved.ReportViewerWebControl.axd

I have no problem with the timeout. I would just like to return the user to
the login page (like when any other page times out), instead of generating
the exception.

Any suggestions would be appreciated.

Hi AG,

As for the reportviewer session timeout issue, here are some of my
underrstanding:

** As long as the session timeout is expected, that way to resolve it may
be check the session validation/timeout in code and then determine whether
to render reportviewer or not

** For session timeout, it is different from FormsAuthentication's timeout
setting. Forms Authentication timeout will cause request be redirected to
login page while session timeout will not.

Therefore, I think you may consider do something as below in your
reportviewr page:

1) check a prestored session variable in session to see whether it exists,
if not, that must means session has been timeout and you'll need to refresh
the page .

2) if the session hasn't been timeout, you can continue to display the page.

Sincerely,

Steven Cheng

Thanks Steven,

I will try that, but it will probably be a long time before I can confirm if
it works. I was unable to duplicate the condition myself, even after leaving
the report on screen for over an hour.
