SqlConnection con = new SqlConnection(CS);
SqlCommand cmd = new SqlCommand();
TaxInvoice ds = null;
SqlDataAdapter adapter;
try
{
    con.Open();
    cmd.CommandText = "FetchInvoice";
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.Parameters.AddWithValue("@invoiceNo", invNo);
    cmd.Connection = con;
    cmd.ExecuteNonQuery();
    ds = new TaxInvoice();
    adapter = new SqlDataAdapter(cmd);
    adapter.Fill(ds);
    ReportDocument rd = new ReportDocument();
    rd.Load(Server.MapPath("Invoicereport.rpt"));
    rd.SetDataSource(ds.Tables[1]);
    CrystalReportViewer1.ReportSource = rd;
}
catch (Exception ex)
{
    throw new Exception(ex.Message);
}
