How can I pass a parameter value from ASP.NET page to a report displayed in a report viewer? Do you have a complete example for this scenario?

Thanx

Ok, I found a solution:
1. During configuring the SQL datasource, at "Configure Data Source Parameters" step, make sure you select correct DbType for the parameter, for value select New Report Parameter.
2. On ASP.NET page that host Report Viewer, add this code:
//Create a new instance of the Report1
Telerik.Reporting.Report report1 = new Report1();
 
//Set a value to a Report Parameter, not to SQL parameter
report1.ReportParameters["ReportParameterName"].Value = int.Parse(Request.QueryString["value"].ToString());
 
//Assign the report to a report viewer
Telerik.Reporting.InstanceReportSource irs = new Telerik.Reporting.InstanceReportSource();
irs.ReportDocument = report1;
ReportViewer1.ReportSource = irs;
