I have an unbound XtraReport that has a subreport control which contains another report. I call "unbound" to a report that has the definition of the fields using a schema but not actually bound to any DataSet, I create a DataTable using a Data Access Layer and then pass that object to the DataSource property of the report.
So, I have the following code:
// (...) Get the data from the db and fill a DataTable
if (table.Rows.Count > 0)
{
report.DataSource = table;
// (...) Get the data from the db and fill a DataTable for the subreport
report.SubPurchaseOrder.Report.DataSource = tableSubReport;
report.ShowPreviewDialog();
}
else
{
MessageBox.Show("No data to show.");
}
But what I get using this approach is the subreport printed very oddly (take a look at the attached pdf, sorry it's in spanish but I think you get the idea).
I've read the DevExpress documentation and maybe I'm not getting the approach right, so my question to you is how to create a report that has one or more subreports but I have to provide the data to fill them using some process external to the reports, such as a Data Access Layer?
Please let me know if the question is not stated correctly or lacks of more info.
EDIT:
I uploaded a sample project with the report with problem here.
I've tried to use parameters of some kind. In the BeforePrint event of the subreport control, I tried:
((XRSubreport)sender).ReportSource.FilterString = "[IdPO_RO] = " + _idPurchaseOrder;
and
((XRSubreport)sender).ReportSource.Parameters["Id"].Value = _idPurchaseOrder;
Of course, for the second, I added a parameter and the filter string the same as the first but using the parameter.
