  Hi,
  
  Migrate from 2010v1 to 2025v2 399 in ASP.NET WebForms NET Framework 4.8.1.

  Using C1ReportViewer from C1.Web.Wijmo.Controls.48.dll
  
  Changes C1WebReport to C1ReportViewer control.

  Old code:

   C1WebReport.ReportError += new C1.C1Report.ReportEventHandler(C1WebReport_ReportError);
      protected void C1WebReport_ReportError(object sender, C1.C1Report.ReportEventArgs e)
      {
          Logger.Info(e.Exception.Message.ToString());
      }

  any alternatives for new C1ReportViewer 2025v2 399 ?

  Hello Enrique,

  The event in newer versions is the same: ReportError

       var report = C1ReportViewer.CreateC1Report();
       report.ReportError += Report_ReportError;
  
  private void Report_ReportError(object sender, ReportEventArgs e)
  {
      Console.WriteLine(e.Exception.Message);
  }
