Datasource in SubReport doesn't work with Q2 2012

[Flavio]

Hi,

   I have a MasterReport with SubReports which as worked with last version, but when I did upgrade to 2012 Q2 in my project, MasterReport stopped working!

The code below was working in last version and now doesn't work. Occurs this error when I set Data Source. 

this.subReport2.ReportSource.DataSource = listOrdersMonth;

Please, I need to solve it!

Thanks!

Hello Flavio,

Since the introduction of the new Report Sources things have changed a bit.  What you have to do here is to create your subreport, assign data source to it and only then use the whole report. The code looks like this:

var mySubReport = new MySubReport();
mySubReport.DataSource = myDataSource;
var irs = new InstanceReportSource { ReportDocument = mySubReport };

this.subReport2.ReportSource = irs;
