Stimulsoft.Report problem in ASP.NET 2.0 SQLServer session

[amator]

Hello!

We are trying to use Stimulsoft.Report, Version=2007.3.21.0 for our ASP.NET 2.0 application.

The session is running in 'SQLServer' mode and we are getting the following exception:

Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.
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.

Why does it try to save 'Stimulsoft.Report.StiReport' in session?
Any workaround?

Thanks, Alex

Please show me your web page (which contain StiWebViewer) and code which you are use for report rendering. For also please set property CacheMode of StiWebViewer to Page.

Thank you.

Thank you, setting CacheMode="Page" resolved the issue!





stReportViewer.Visible = true;

StiReport report = new StiReport(); //stReport.GetReport();
report.Load(path + "APP_DATA\\" + reportFile);

//Clear the list of databases
report.Dictionary.Databases.Clear();

//Add the database and specify its name and the connection string
report.Dictionary.Databases.Add(new Stimulsoft.Report.Dictionary.StiSqlDatabase("Connection", connection));


report.Compile();
report.DataSources["dsDeductiblesDifferences"].Parameters["@dealerID"].ParameterValue = this.DealerUser.DealerID;
stReportViewer.Report = report;
