Scripting inside report

See original GitHub issue


I am running netcore 3 in Mac OSX

I made a simple report using Designer Community following documentation. The Script C# looks like this inside the .frx file:

<ScriptText>using System;
using System.Collections;
using System.Collections.Generic;
using System.ComponentModel;
using System.Windows.Forms;
using System.Drawing;
using System.Data;
using FastReport;
using FastReport.Data;
using FastReport.Dialog;
using FastReport.Barcode;
using FastReport.Table;
using FastReport.Utils;

namespace FastReport
  public class ReportScript
    private void EstadoResultado_BeforePrint(object sender, EventArgs e)
      if (((Int16)Report.GetColumnValue(&quot;demo&quot;)) &gt; 0) {
        Demo.TextColor = Color.Red;

The report works fine in Preview from Designer Community.

I developed a simple Web API project using netcore 3.1 following one of your samples. The API use PDFSimpleExport to generate a PDF from report:

            PDFSimpleExport pdf = new PDFSimpleExport();
            MemoryStream memStream = new MemoryStream();
            report.Export(pdf, memStream);

This code works perfectly with a report with no Scripting. But if I try with the before scripted report I have:

An unhandled exception has occurred while executing the request.
FastReport.Utils.CompilerException: (21,24): Error CS0012: The type 'Color' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Drawing.Primitives, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
(21,36): Error CS0103: The name 'Color' does not exist in the current context

   at FastReport.Code.AssemblyDescriptor.InternalCompile()
   at FastReport.Code.AssemblyDescriptor.Compile()
   at FastReport.Report.Compile()
   at FastReport.Report.Prepare(Boolean append)
   at FastReport.Report.Prepare()

How can we add the reference to that assembly? How can we add the needed assembly referenced in the Report Script? Everything inside the Script is pure NetCore, I mean will run in any paltform?

sorry used nuget and got opensource and compat Using winForms .net framework 4.6.1 and vs2022 … trying to replace winforms reporting so I can upgrade it. 2021.3.1 appears to work for me.

@drechema In the last update we made the automatic addition of assembly if they are known to .Net. In case of unknown assemblies, please add (do not replace) them in Report.ReferencedAssemblies before preparing the report (before Report.Prepare()).
