Display a Report from a selected grid Item

Question

Hi everyone, 

I have  a grid which the User can select an Invoice Item to view.

 

I have the code below which returns an empty report. Thanks.

 

 

try {

var selectedinvoice = InvoiceView.GetFocusedRow() as Invoice;

if (selectedinvoice == null) return;

rptInvoice InvoiceChoice = new rptInvoice();

InvoiceChoice.DataSource = _invoiceTransactionService.GetById(selectedinvoice.InvoiceId);

ReportPrintTool tool = new ReportPrintTool(InvoiceChoice);

tool.ShowPreview();

} catch (Exception Errhand) {

MessageBox.Show(Errhand.Message);

}
