  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.

  In VS2022 IDE, I get 'C1.C1Report.Section error message about convert string to ‘C1.C1Report.Section’

  report.Sections.Contains(“TIPO_Header”)

          //    if (this.C1GridView1.GroupedColumns.Count > 0)
          //    {
          //        C1WebReport.Report.Groups[0].GroupBy = ((C1BoundField)this.C1GridView1.GroupedColumns[0]).DataField;
          //        C1WebReport.Report.Groups[0].Sort = C1.C1Report.SortEnum.NoSort;
          //        C1WebReport.Report.Sections["TIPO_Header"].Fields["Field15"].Value = ((C1BoundField)this.C1GridView1.GroupedColumns[0]).DataField;
          //    }
          if (p.IsGrouped && !string.IsNullOrEmpty(p.GroupedFieldName))
          {
              report.Groups[0].GroupBy = p.GroupedFieldName;
              report.Groups[0].Sort = C1ReportV48.SortEnum.NoSort;
              if (report.Sections.Contains("TIPO_Header") &&
                  report.Sections["TIPO_Header"].Fields.Contains("Field15"))
              {
                  report.Sections["TIPO_Header"].Fields["Field15"].Value = p.GroupedFieldName;
              }
          }

       if (!string.IsNullOrEmpty(p.ChartImagePhysicalPath) &&
           //report.Sections.Contains("Detail") //&&
           report.Sections["Detail"].Fields.Contains("lblChart"))
       {
           report.Sections["Detail"].Fields["lblChart"].Picture = p.ChartImagePhysicalPath;
           report.Sections["Detail"].Fields["lblChart"].PictureAlign = C1ReportV48.PictureAlignEnum.CenterMiddle;
           report.Sections["Detail"].Fields["lblChart"].PictureScale = C1ReportV48.PictureScaleEnum.Scale;
       }

  any suggestions ? THANKS !! in advanced

  Hello Enrique,

  In newer version, Contains() only accepts a Section object, not a string. There’s no overload for string-based lookup.
  
  To resolve, create a helper extension method:

  public static class SectionCollectionExtensions
  {
      public static bool Contains(this C1.C1Report.SectionCollection sections, string name)
      {
          foreach (C1.C1Report.Section section in sections)
          {
              if (string.Equals(section.Name, name, StringComparison.OrdinalIgnoreCase))
                  return true;
          }
          return false;
      }
  }

  Then your existing code works without any changes.

  Here is a sample with the implementation. (see Report_Sample.zip)

  Regards,
  
  Uttkarsh.
