Question

How do I programmatically set the data source for the ASP.NET ReportViewer control?

I have a VS 2008 ReportViewer control and want to switch between a couple of different reports.

I can switch reports by setting the report source and refreshing the control, but I can’t see where to set the data source.

Each report has its own data source, and if I configure them initially when the control is built it is fine, but I need to switch between them.

I assume the question is about ReportViewer control.

reportViewer.LocalReport.DataSources.Clear();
reportViewer.LocalReport.DataSources.Add(new ReportDataSource("dsname", source));

"dsname" is the name of the data source, you can find it .rdlc file. source is the variable with data you want to show in the report.
