ReportViewer: DataSource issue with Subreports

[billygotee]

Hi, I posted an issue previously that was entirely accurate.

I have a master report called "MasterReport.r dlc" and a subreport
called "Subreport.rdlc ". MasterReport.rd lc has a single subreport
with name Subreport and refers to Subreport.rdlc. I add a data source
in the VS 2k5 report environment to Subreport.rdlc. This data source
has name "SubreportI nfo" and is an object of type SubreportInfo.

First, say I set my ReportViewer.Lo calReport.Repor tPath to
Subreport.rdlc and add the following code to my form load function,
right before ReportViewer.Re freshReport:

ReportDataSourc e SubreportDataSo urce;
BindingSource SubreportBindin gSource = new BindingSource() ;
SubreportDataSo urce = new ReportDataSourc e("SubreportInf o",
SubreportBindin gSource);
ReportViewer.Lo calReport.DataS ources.Add(Subr eportDataSource );
SubreportBindin gSource.DataSou rce = SubreportInfo;

When I compile and run, this displays just fine. Now let's say I set
my ReportViewer.Re portPath to "MasterReport.r dlc" and make
Subreport.rdlc blank (with no data sources). This will also compile
and display fine. But if I put the data source back in Subreport.rdlc
as described above, and add another line of code to link the following
event to ReportViewer.Lo calReport.Subre portProcessing:

void SubreportProces sing(object sender, SubreportProces singEventArgs
e)
{
e.DataSource.Ad d(SubreportData Source);
}

I will have, upon running, a report that says nothing but "Error:
Subreport could not be displayed".

What am I missing?

Thank you very much,
Brandon
