Hi Ileana,

The known reasons for such an error are listed in the Report is unavailable or session has expired error message KB article, which you say you've read. Unfortunately we cannot offer anything concrete if you do not provide us with more information on your project and how/when does the issue occur. For example, does this happen immediately when you open the RadWindow with the report viewer or does it happen after some inactivity? In such case, check the session expiration in your web.config.
Also does it happen everytime or on random basis, if the latter check the machine and IIS logs to verify whether there is some error or your application pool has not been recycled.

The scenario is this, I have a radwindow, where is the report viewer, and I assign the report to show through code, because they are two reports in which the user can choose (as show in the picture).
The throws errror when I assign the report.
sometimes immediately open the radwindow
and others when I put the report parameters

Hi Ileana,

You have marked our previous answer as answer, which means that no further help is expected/required. Please check the How to: Add report viewer to a web page help article that shows how to assign report to the viewer programatically and compare it to how you do it.

If the problem persists and it happens on more than one machine, please prepare a sample and open official support ticket where you can attach it for us to review.

sorry I had not noticed that mark that answer, the problem is in report viewer, now I want to export directly the report 
to pdf, whitout report viewer, I search and I have a few examples 
I can export it but the file is blank.
I don't understand how I can pass the report with parameters, like with crystal reports
how I can assign my report.tdx with my variable report1

Dim report1 As New Telerik.Reporting.Report
Dim uriReportSource As New Telerik.Reporting.UriReportSource()
              
uriReportSource.Uri = Server.MapPath("PCB_Bitacora" & IIf(rcbTypeReport.SelectedValue = "Listado Por Maquinas", "", "_Grafica") & ".trdx")
uriReportSource.Parameters.Add(New Telerik.Reporting.Parameter("@Fecha1", Convert.ToDateTime("11/19/2012").ToShortDateString))

uriReportSource.Parameters.Add(New Telerik.Reporting.Parameter("@Fecha2", Convert.ToDateTime("11/22/2012").ToShortDateString))

report1.DataSource = uriReportSource

SaveReport(report1, Server.MapPath("UploadedFiles\") + "Myreport.pdf ")

Sub SaveReport(report As Telerik.Reporting.Report, fileName As String)
  Dim reportProcessor As New Processing.ReportProcessor()
  Dim instanceReportSource As New Telerik.Reporting.InstanceReportSource()
  instanceReportSource.ReportDocument = report
   Dim result As Processing.RenderingResult = reportProcessor.RenderReport("PDF", instanceReportSource, Nothing)
        Using fs As New FileStream(fileName, FileMode.Create)
            fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length)
        End Using
End Sub

Hello Ileana,

There is some misunderstanding about which is what and where it can be used. Telerik.Reporting.Report is a CLR object, while report.tdx is XML report definition i.e. XML markup.

The Report Sources present uniform way to access Telerik Reports, they are not a data source. When you have an UriReportSource and you set its Uri to a .trdx file, all that is left is to pass that report source to the ReportSource of the report viewer (if you want to display it in viewer) or pass it to the appropriate method (in your case RenderReport). Note that the RenderReport Method accepts any ReportSource, not only instance, so you can pass the UriReportSource directly to that method.

On a side note, if you prefer to work with CLR types and objects, you can deserialize the xml report definition as shown in the Serializing Report Definition in XML help article and proceed from there like you would normally do following the basic concepts of the programming language and the .NET platform.

Kind regards,
Steve
