Hi All,

I need to pass a session variable to a report.  If I could access the session variables from the report that would be good too.  Any ideas how to do that?

Thanks,
Darren

Hi Darren ,

In the following example you can see how to access a session variable and pass it to the report parameter:


report1.ReportParameters("InvoiceID").Value = System.Web.HttpContext.Current.Session("InvoiceID")

Let me know whether the proposed solution helps.

All the best,

Doesn't seem to work directly in the report.  I guess there's not a way to access the session variables directly from the report?

Hi Darren ,

The following code snipped demonstrates how to access a session variable from a Report.

System.Web.HttpContext.Current.Session["InvoiceID"];

Just have in mind that if you are using a separate class library to create the Report you will have to reference the System.Web.dll assembly.

I have attached a sample project.

If I have a dataset in session I'm assuming I can do the same thing and use it in my NeedDataSource event.....

Telerik.Reporting.Processing.Table table3 = (Telerik.Reporting.Processing.Table)sender;
            DataSet dataSet3 = new DataSet();
            dataSet3 = (DataSet)System.Web.HttpContext.Current.Session["PreviewInvoice"];
            table3.DataSource = dataSet3;

Assuming there is a valid dataset within my session["PreviewInvoice"] variable, will this work?

Hi Bill,

I tested to open Peter Raykov's attachment from 18 Mar 2010 11:26 AM in VS 2019. The Visual Studio 2019 successfully converted the solution and opened it - see the attached screenshot.

Note that this thread is from 2010 and the sample was created with Telerik Reporting version 4.0.10.312. It is a Web Site project that cannot be automatically upgraded to a newer version. The sample demonstrates an approach that is suitable only for the legacy Web Forms Report Viewer. This viewer is no longer actively developed.

For WebForms projects I strongly recommend using the Html5 Web Forms Report Viewer instead. Here are some useful links that will help you start with it:

Consider also opening a Support ticket where to explain your requirement. We may give further advice on how to achieve it with the newer viewer.

Regards,
Todor
