This example shows a drill-through report in a WPF application. This report type keeps the original report compact while still allowing access to more detailed information.
The drill-trough report type requires a parameter binding to display connected data. You also need to set a filter string in the detail report to display product records for the selected category. See the guide for more detailed steps: Create Drill-Through Reports.
In the app, you can click a Category entry to invoke a detail report with products:
Use breadcrumbs to navigate back to the original report. The breadcrumb control automatically appear below the Document Viewer toolbar:
