Another sub-report binding question

[Michael Eaton]

I am binding my main report to an instance of an object that looks like this:

public class foo {
    public Bar Header { get;set; }
    public List<Baz> ListOfStuff { get;set;}
}

I have a sub-report that will display .ListOfStuff, but I'm at a loss on how to bind the sub-report so it has access this data from the main report.

At a high-level, this is how my main report is binding to the original source:

                var report = new TestReport();
                var ods = new Telerik.Reporting.ObjectDataSource();
                ods.DataSource = instanceOfFoo;
                report.DataSource = ods;
               
                instanceReportSource.ReportDocument = report;
                ReportViewer.ReportSource = instanceReportSource;

My sub-report doesn't have a DataSource set, so I've tried using NeedDataSource, but I'm not sure what exactly I need to do to bind to the parent data.

I'm sure I'm missing something really simple, but at this point, I'm stuck.

Solved.

It boils down to me being an idiot. :-)

I was fetching my data from a service. The service was returning data in a slightly different format than I was expecting.

Binding works as expected.

In my sub-report, I simply added a binding that looks like:

DataSource, ="ReportItem.Parent.DataObject"

and my sub-report has the data I need.
