  I’m working with AR12 trial to evaluate an upgrade from AR10. In AR10, I reworked your EndUserDesigner into a multi-tabbed editor which relies on the ability to new up a Designer.

  We work exclusively with SectionReports, but code that once worked in AR10 is now giving unexpected runtime errors. The following code used to work just fine:

  var page = new TabPage("SomeTabIndexName");
  var designer = new Designer();
  var sectionReport = (SectionReport)designer.Report
  sectionReport.Script.Language = "VB.NET";
  //etc., etc.
  

  It compiles fine, since the Designer’s .Report is an object at compile time. However, at runtime it suddenly becomes a PageReport and cannot be cast into a SectionReport. The Designer’s ReportType is read-only, and there are no constructors to allow me to specify a ReportType.

  Am I doing something wrong, or is this an unintentional breaking change in AR12? How can I new up a Designer for use with SectionReports?

  Hello,

  This occurs since the designer tries to open a RDL report by default. If you set the default report to open as a Section Report to avoid above issue. You can use the following line of code.

  
  var page = new TabPage("SomeTabIndexName");
  var designer = new Designer();
  designer.NewReport(DesignerReportType.Section);
  var sectionReport = (SectionReport)designer.Report
  sectionReport.Script.Language = "VB.NET";
  
  

  Hope it helps.

  Thanks,
