  I am upgrading my C1Report(s) to C1FlexReport(s). Most everything has an appropriate equivalent. I have found a problem with a subreport. I dynamically set the connection string and recordset of the datasource using code.

  rpt.Fields[“rsubRegistrationExtraCharges”].Subreport.DataSource.ConnectionString = connection.ConnectionString;

  In C1Report this worked great. The documentation for the C1FlexReport seems to indicate that this will work but I get an error message at design time that says:

  FieldBase’ does not contain a definition for ‘Subreport’ and no accessible extension method ‘Subreport’ accepting a first argument of type ‘FieldBase’ could be found

  What is the resolution of this change in the object model of the C1FlesReport

  Hello George,

  Subreport property is under SubreportField class that inherits FieldBase class. You can use the code snippet given below to achieve your desired result :

  SubreportField srField = (SubreportField)_c1flxr.Fields["rsubRegistrationExtraCharges"];
  C1FlexReport rptSubreport = srField.Subreport;
  rptSubreport.DataSource.ConnectionString = connection.ConnectionString;
  rptSubreport.DataSource.Recordset = _dataTable;
  

  You can learn more about how to use SubReport in FlexReport by the product sample name “SubreportDataSource” which is found in your system at location : \Documents\ComponentOne Samples\WinForms\v4.0\C1FlexReport\CS\SubReportDataSource
