You cannot use the Crystal Reports windows forms viewer on the web. Use the PdfViewer instead like this:
var report = new ReportDocument(); report.FileName = Application.MapPath("CrystalReport1.rpt"); this.pdfViewer1.PdfStream = report.ExportToStream(ExportFormatType.PortableDocFormat);
Please see the screenshot of ASPNetReportViewer project, I have downloaded from Support Link to use ReportViewer control but the project is opening up as normal Windows application.
