Report inheritance in Fast Report Online Designer

mtecnic

Hello,

I've tried to open a report that inherits from another using Fast Report Online Designer, but I couldn't manage to get it working.

The reports I used are the ones on this github repository https://github.com/FastReports/FastReport/tree/master/Demos/Reports, the Inherited Report - base.frx and Inherited Report.frx.

The code I used is the following:

[HttpGet]

[Route("getReport")]

[Consumes(MediaTypeNames.Application.Json)]

public async Task<IActionResult> GetReport()

{

           try

           {

               WebReport webReport = new WebReport();

               webReport.Width = "1000";

               webReport.Height = "1000";

               string reportPath = Path.Combine(_hostEnvironment.ContentRootPath, "App_data", "Inherited Report.frx");

               string dataPath = Path.Combine(_hostEnvironment.ContentRootPath, "App_data", "nwind-employees.xml");

               string baseReportPath = Path.Combine(_hostEnvironment.ContentRootPath, "App_data", "Inherited Report - base.frx");

               webReport.Report.BaseReportAbsolutePath = baseReportPath;

               //webReport.Report.BaseReport = "Inherited Report - base.frx";

               DataSet dataSet = new DataSet();

               dataSet.ReadXml(dataPath);

               webReport.Report.RegisterData(dataSet, "NorthWind");

               webReport.Report.Load(reportPath);

               webReport.Mode = WebReportMode.Designer; // Set the web report object mode - designer display

               webReport.DesignerLocale = "es";

               webReport.DesignerPath = "/WebReportDesigner/index.html"; // Specify the URL of the online designer

               webReport.DesignerSaveCallBack = "/fr/SaveDesignedReport"; // Set the view URL for the report save method

               webReport.Debug = true;

               ViewBag.WebReport = webReport; // pass the report to View

               return View("~/Views/FastReport/ReportDesigner.cshtml");

           }

           catch (Exception e)

           {

               return Ok();

           }

       }

And when I open the designer it shows the following error:

If I open another report without inheritance it works fine.

So my question is: How can we set a base report in Fast Report Online Designer and How can I create a base report?

Thanks!
