Debug Scripts in Visual Studio

This topic describes how to debug scripts used within the End-User Report Designer.


Report scripts are not secure. We recommend that you use expression bindings instead.

  1. Open your application that contains the End-User Report Designer. Do one of the following depending on the application target framework:

    • .NET Framework – add the <system.diagnostics> section to the application’s configuration file as shown below:

      <?xml version="1.0" encoding="utf-8"?>
                  <add name="AllowDebugXtraReportScripts" value="BreakWhenDebuggerAttached"/>
    • .NET 6+ – create a runtimeConfig.template.json file in the application’s folder and put the following settings into this file:

          "configProperties": {
              "AllowDebugXtraReportScripts": "BreakWhenDebuggerAttached"
  2. Run the application.

  3. Start Visual Studio and select Debug | Attach to Process in the toolbar.

    Attach to Process menu

  4. Select your running application in the invoked Attach to Process dialog.

  5. Return to the application with the End-User Report Designer and switch to the Preview tab. This operation opens a temporary generated class with all report elements and script code in Visual Studio.

    Set breakpoint

    You can debug the script code in this tab (for example, use breakpoints). To see a file location folder, place a cursor over this file.
