• Under Use these additional criteria, you may optionally choose to search for the whole word or match the case of the search string while searching in the report.
• Click the Search button to see the results appear in the Find results list.
• Click an item in the list to jump to that item in the report and highlight it.

To start a new search or clear the current search results, click the Clear button under the Find results list.

Document map pane

The Documents map pane sis enabled for reports where the Label property or the Document map label is set. This pane displays each value for the text box, group, or sub report that you label, and you can click them to navigate to the corresponding area of the report in the Viewer.

If a report does not have the Label property or Document map label set, the Documents map panes does not appear in the sidebar.

2. Enter a value or set of values and click View report, to filter the report data and display the report.

If a report does not have parameters, the Parameters pane does not appear in the sidebar.

Display the report in the WPF Viewer

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 9 Page Report, ActiveReports 9 RDL Report, ActiveReports 9 Section Report (code-based) or ActiveReports 9 Section Report (xml-based). This adds the necessary references to your project.
4. From the Toolbox ActiveReports 9 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.

Keyboard Shortcuts

Running WPF Viewer in Partial Trust

You can run a WPF Viewer Browser Application in Partial Trust by customizing the permission set in the app.mainfest file. While customizing the permission set, some of the permissions are to be set explicitly like MediaPermission, UIPermission, etc. Follow these steps to learn how to run a WPF Viewer application in partial trust.

Note: These steps assume that you have already created a WPF Browser Application that contains the WPF Viewer control.

1. In the Solution Explorer, right-click your WPF Browser Application and select Properties.
2. On the properties page that opens, go to the Security tab.
3. On the Security tab, set Zone your application will be installed from to Custom and click the Edit Permissions XML button. This opens the app.mainfest file.
4. In the app.manifest file, replace the existing xml code inside the <applicationRequestMinimum> </applicationRequestMinimum> tags with the following code.

   Code

   XML

   Copy Code

   <defaultAssemblyRequest permissionSetReference="Custom" /> <PermissionSet class="System.Security.PermissionSet" version="1" ID="Custom" SameSite="site"> <IPermission class="System.Data.SqlClient.SqlClientPermission, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" /> <IPermission class="System.Data.OleDb.OleDbPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" /> <IPermission class="System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" /> <IPermission class="System.Security.Permissions.MediaPermission, WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" version="1" Audio="SafeAudio" Video="SafeVideo" Image="SafeImage" /> <IPermission class="System.Security.Permissions.UIPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" /> <IPermission class="System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" /> <IPermission class="System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" /> <IPermission class="System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" />> <IPermission class="System.Security.Permissions.StrongNameIdentityPermission, , mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" /> </PermissionSet>
