Im try your method in the past, but it never function with me.
So i found a better solution:
*//load my form and create a ReportDocument instance*
frmRelatorio fr = new frmRelatorio();
ReportDocument rptDoc = new ReportDocument();
*//load de RPT file*
rptDoc.Load(Core.pastaLocal + @"Relatórios\balanco_contas.rpt");
*//create my object that will return de dataSet to me*
BalancoContas cr = new BalancoContas();
*//call the method that return a dataset to me and fill the first table of
my report (0)*
rptDoc.Database.Tables[0].SetDataSource(cr.listarRelatorio());
fr.rptViewer.ReportSource = rptDoc;
*//show the form with crystal reports viewer*
fr.ShowDialog();
------------------------------------------------------------------------------------------------------------------------
To do it, you need create a new DataSet from file -> new -> dataset.
Put the columns like your database table.
Fill the first table of your reports (table 0):
rptDoc.Database.Tables[0].SetDataSource( <your dataset here> );
Set the crystal report document to crystal reports reportSource:
form.rptViewer.ReportSource = rptDoc;
To simple.
