ReportViewer for ASP.NET Web Forms includes the C1ReportViewer control which is a control that allows users to view and browse reports or documents generated by ComponentOne reporting products in a Web application. The viewer's server side code uses C1Report assembly (C1.C1Report.4.dll), the same DLL that is used by ComponentOne Reports for WinForms) to generate documents and reports, and to serve pages to the viewer.

The report viewer's class is C1.Web.Wijmo.Controls.C1Report.C1ReportViewer. The viewer shows document and reports using an innovative technology that ComponentOne calls Web Paper. Web Paper technology allows the reports to be displayed with very high fidelity while preserving the ability to select, copy, and search text.
