Changing a report in ReportViewer at runtime in a C# application can be achieved by setting a new report definition to the ReportViewer control.

To play the demo, you need to create two local reports, then add Report Viewer control from your visual toolbox to your windows forms application.

//This code will define a report at runtime
reportViewer1.Reset();
reportViewer1.LocalReport.ReportEmbeddedResource = @"D://Report1.rdlc";
// Refresh the report viewer to display the new report
reportViewer1.RefreshReport();

You can also, set data source, parameters to your local report

For WebForm only change

reportViewer1.LocalReport.ReportEmbeddedResource = MapPath("Report1.rdlc");

Depend on different DataSources, you should define the DataSource then bind it to the ReportViewer
