My .NET web app has a DataSet in memory. It includes several tables.
 
How can I hook Crystal Reports XI into this data?
Can it be done without writing the dataset to a physical file?
 
I know basically how to use the ReportDocument in .NET code. But I don't know the best way to pass a DataSet in memory to CR.
 
Much thanks

I haven't worked with the web viewer, but in WinForms I add a property to the form with the viewer.  This property will contain the dataset I want to use for the report.
 
In the "Set" for the property, I set the report document's datasource to the dataset.
 
In C# the code to open the new for looks something like this:
ReportViewer viewer = new ReportViewer();
viewer.DataSrc = rptDS;
viewer.Show();
 
In the viewer form, the code looks like this:
private ReportDocument myReport;
public CrystalDocReportViewer(DataSet ds)
{
  InitializeComponent();
   rpt = new MyReport();
}
public DataSet DataSrc
{
  set
  {
    rpt.SetDataSource(value);
    viewer.ReportSource = rpt;
  }   
}
