ReportViewer Control problem


N

nitadmin

Hi,


I created a new aspx page and I added the Report Viewer Control.
I am using Visual Studio 2005, >Net Framework 2.0
I have already published report on my Report Server.
My report server is running on a Windows 2003 server, running SQL 2005
and Report Services 2005.


When I access the webpage from Internet Explorer, I keep getting this
exception.

In remote mode, the Report Viewer control requires session state be
enabled or Report Server connection information specified in the
config file.
Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more
information about the error and where it originated in the code.

Exception Details:
Microsoft.Reporting.WebForms.MissingReportServerConnectionInformationException:
In remote mode, the Report Viewer control requires session state be
enabled or Report Server connection information specified in the
config file.




Why does this happen? What am I doing wrong?
Is my code behind correct? Is my web.config file correct?

thanks,
nitadmin
