1. I have all the data in a DataTable. I have created the CrystalReport document using VS2005 by using labels, boxes etc. Now do I   have to use formula fields to set the values in the document.

2. When I have all the documents created how can I send them all to the CrystalReportViewer at once for viewing?

1. Create a new form with a CrystalReportViewer on it
2. Create a new instance of your report and call Load() on it
3. Set the ReportDocument property ont he CrystalReportViewer to your new report instance
