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
