The ActiveReports WPF Viewer is a custom control that allows to easily view section, RDL and page report layouts.

This walkthrough is split up into the following activities.

When you have completed this walkthrough, you will have the ActiveReports WPF Viewer displaying a report that looks similar to the following.

To create a WPF application in Visual Studio

  1. On the Visual Studio File menu, click New Project.
  2. In the New Project dialog that appears, select WPF Application in the list of templates.
  3. Specify the name and location of the project and then сlick the OK button.
  4. In the Visual Studio Solution Explorer, right-click YourProject and select Add, then New Item.
  5. In the Add New Item dialog that appears, select the ActiveReports 10 Page Report and create the rptSingleLayout report as described in the Single Layout Reports walkthrough.

To add the WPF Viewer control

  1. In Solution Explorer, open MainWindow.xaml.
  2. From the Toolbox ActiveReports 10 tab, drag the Viewer control and drop it on the design view of MainWindow.xaml.
  3. In the Properties window, set the properties of the Viewer control as follows.
    Property Name Property Value
    HorizontalAlignment Stretch
    VerticalAlignment Stretch
    Margin 0
     
  4. In the Properties window, rename the Viewer control to viewer1.

To load a report to the WPF Viewer

  1. In the Solution Explorer, select the rptSingleLayout report you have created.
  2. In the Properties window, set Copy to Output Directory to Copy Always.
  3. On MainWindow.xaml, with the viewer selected, go to the Properties window and double click the Loaded event.
  4. In the MainWindow code view that appears, add code like the following to the viewer1_loaded event to bind the report to the viewer. This code shows an .rdlx report being loaded but you can use an .rpx report as well.
    Visual Basic.NET code. Paste INSIDE the viewer1_Loaded event in MainWindow.xaml.vb.
    Copy Code 
    Viewer1.LoadDocument("rptSingleLayout.rdlx")
    C# code. Paste INSIDE the viewer1_Loaded event in MainWindow.xaml.cs.
    Copy Code 
    viewer1.LoadDocument("rptSingleLayout.rdlx");
Note: For an example of other ways to bind a report to the WPF Viewer, see the LoadDocument method in the Class Library documentation.
Note: To avoid evaluation banners appearing at runtime, license your ActiveReports WPF Application project. You can find information on licensing in License Your ActiveReports.

  5. On MainWindow.xaml before the opening <Grid> tag, add the following code.
    Paste to the XAML view of MainWindow.xaml before the opening <Grid> tag
    Copy Code 
    <Window.Resources>
