Set up your WPF Application project by using the following steps.

  1. Create a new WPF Application project or open an existing one.
  2. For a new project, in the Visual Studio Solution Explorer, right-click YourProject and select Add, then New Item.
  3. In the Add New Item dialog that appears, select the ActiveReports 8 Page Report, ActiveReports 8 Section Report (code-based) or ActiveReports 8 Section Report (xml-based). This adds the necessary references to your project.
  4. From the Toolbox ActiveReports 8 tab, drag the Viewer control and drop it on the design view of MainWindow.xaml.
    Note: Dragging the Viewer control to the design view of MainWindow.xaml automatically adds the corresponding reference to the licenses.licx file.
  5. In the Properties window, with the report selected, set Copy to Output Directory to Copy Always.
  6. On MainWindow.xaml, with the viewer selected, go to the Properties window and double click the Loaded event.
  7. In the MainWindow code view that appears, add code like the following to the viewer1_loaded event to bind the report to the viewer. Each of these code snippets presumes a report in the project of the type indicated with the default name. (If you have renamed your report, you need to rename it in the code as well).
    Note: Refer to the LoadDocument method to see other ways to load a report in WPF Viewer.
