Reporting for WPF - How to load a DevExpress Reporting Document (PRNX) to the Document Preview

This example illustrates how to preview a DevExpress Report document (*.PRNX) using the WPF Document Viewer.

The Document Preview Control supports the following document sources:

• DevExpress Reports.
• DevExpress Report Documents: Store Report Documents. It can be:
  • A stream containing report document data: Saving Documents to a Stream;
  • A string containing a path to a PRNX file which stores report document data: Saving Documents to a File.
• An object implementing the ILink interface: WPF Controls | Printing Links.

Example Overview

To preview a document:

• Generate a document from a report by calling the PrintingSystemBase.SaveDocument method:

private void button1_Click(object sender, System.EventArgs e) {
    // Create a report instance. 
    XtraReport1 report = new XtraReport1();

    // Generate a complete report document.
    report.CreateDocument();

    // Save the document to a file. 
    report.PrintingSystem.SaveDocument(@"...\Invoice.prnx");
}

• Assign a path to the resulting document or a stream with document data to the DocumentViewerControl.DocumentSource property at runtime:

documentPreview.DocumentSource = @"...\Invoice.prnx";
