I'm using visual studio 2010 and crystal report 13.0.18.2192 version, But I have a problem when I try to pass a new parameter field to existing report It won't appear, give an error.. I want to pass The Shop name as the top of the report, I tried it by passing as a textobj in the report but I will print correctly by print preview but when I run it inside the program it prints like as my old crystal report (with out shop name).

What I have tried:

double discountP = 0;
if (txtDis.Text.Length > 0 && txtDis.Text!="0")
    discountP = double.Parse(txtDis.Text);
string path2="";
if ((InvNo.StartsWith("CAS-V") || InvNo.StartsWith("INV-V")) && needVat && discountP == 0)
path2 = Path.Combine(Environment.CurrentDirectory, @".\CrystalReporInvoiceVat.rpt");
else if(discountP>0)
path2 = Path.Combine(Environment.CurrentDirectory, @".\CrystalReporInvoiceVat.rpt");
else
 path2 = Path.Combine(Environment.CurrentDirectory, @".\CrystalReportSalesInv.rpt");
rptDoc.SetDataSource(ds1);
rptDoc.DataSourceConnections.Clear();
rptDoc.SetParameterValue("ShopName", "NEW SINGHE HARDWARE STORES");
//rptDoc.SetParameterValue("ShopAdd", "29 Karalliyadda Theldeniya Tel:081-2050044 081-2050040 077-3777713");
rptDoc.SetParameterValue("CusName", txtName.Text);
rptDoc.SetParameterValue("CusID", txtInvTo.Text);
rptDoc.SetParameterValue("CusAdd1", txtCusDetails1.Text);

This solution was working for me. just have a try.

 var date = DateTime.Today();
 ReportDocument report = new ReportDocument();
 CrystalReportViewer crystalReportViewer1 = new CrystalReportViewer();

//Attach datasource etc. here
 report.SetParameterValue("@EndDate", date);
 crystalReportViewer1.RefreshReport();
