Run Demo: ASP.NET AJAX Reporting

The Web Document Viewer is a component that displays an interactive preview of a document generated from a report that is designed in the DevExpress Reporting platform. The Document Viewer allows the user to view, print, and export the report document.

The Document Viewer is designed to display only DevExpress Reports. Our reports use the XML-based report file format, which is not compatible with third-party reporting applications. We offer a utility to convert third-party reports to DevExpress format. Refer to the following help topic for more information: Convert Third-Party Reports to DevExpress Reports.


Use the XRRichText report control to display RTF and DOCX files, and the XRPdfContent report control to display PDF files in a report. You can use other DevExpress components to display different document types in your apps. Review the following help topic for more information: DevExpress Document Viewers for Web.
