Here is the exact error that is reported when telerik and the session state are configured(it's attached as image file). When using telerik reporting tool..I'm using sql datasouces to get values and here is the all code that I used..I used designer part to create the report page..
This is code for aspx page which has Report Viewer
and this is the aspx.cs codebehind part of the page
namespace TelerikReporting{ using System; using System.ComponentModel; using System.Drawing; using System.Windows.Forms; using Telerik.Reporting; using Telerik.Reporting.Drawing; using System.Configuration; using System.Data.SqlClient; using DataService.ConnectionFactory; public partial class PropRep : Telerik.Reporting.Report { public PropRep(int ID) { // // Required for telerik Reporting designer support // InitializeComponent(); this.ReportParameters["ID"].Value = ID; PropTest.Parameters["@ID"].Value = ID; PropTest.ConnectionString = ConnectionFactory.GetConnectionString(ConnectionType.SQLConnection); // // TODO: Add any constructor code after InitializeComponent call // } }}This is code for aspx page which has Report Viewer
<html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title></head><body> <form id="form1" runat="server"> <div> <telerik:ReportViewer ID="ReportViewer1" Width="100%" Height="800px" runat="server"></telerik:ReportViewer> </div> </form></body></html>and this is the aspx.cs codebehind part of the page
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls; public partial class Reporting_Report : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { if (Request.QueryString["PID"] != null) { int ID = Convert.ToInt32(Request.QueryString["PID"].ToString()); Telerik.Reporting.InstanceReportSource instanceReportSource = new Telerik.Reporting.InstanceReportSource(); instanceReportSource.ReportDocument = new TelerikReporting.PropRep(ID); this.ReportViewer1.ReportSource = instanceReportSource; } } }}2 Answers, 1 is accepted

Hi Veysel,
When out-proc session state is used the report should have a default constructor (constructor without parameters). For more information on the topic check out the Design Considerations for Out-proc Session State help article.
