how to genarate invoice crystal report using dataset with multiple tables C# ASP.NET in vs 2010

hello everyone...

I m currently using vs2010. In that i want to generate crystal report for invoice.

My database tables are Table 'A' and Table 'B' which are as follows

-----------------------------------------------------------------
Table 'A'
------------------------------------------------------------------
invoiceid  | invoicedate | subtotal | tax1  | tax2 | Grand Total

   1          07/13/2012     500.00    VAT    CST      700
   2          09/08/2011     800.00    VAT    Sales    1000
------------------------------------------------------------------


-----------------------------------------------------------------
Table 'B'
------------------------------------------------------------------
invoiceid  | invdetid  | itemno | itemname  | qty | rate  | amount

   1            1         1        item A      5     10.0    50.0
   1            2         2        item B      3     5.00    15.00 
   2            3         1        item A      10    12.00   120.00 
------------------------------------------------------------------

so here..i m using dataset in which, i m taking two tables,i.e. Table 'A' and
Table 'B'
and my query in procedure is

select A.invoiceid,A.invoicedate,A.subtotal,A.tax1,A.tax2,A.Grand Total,
       B.invoiceid,B.invdetid,B.itemno,B.itemname,B.qty,B.rate,B.amount
 from Table A,Table B
where A.invoiceid=B.invoiceid

so by this query i m getting result by invoice number.

My aspx.cs code is
---------------------

Con = new SqlConnection(strConnString);
                Con.Open();
                cmd.CommandText ="TestReport";
                cmd.CommandType = CommandType.StoredProcedure;
                
                cmd.Connection = Con;
                adapter = new SqlDataAdapter(cmd);
                ds = new DataSet();
                adapter.Fill(ds,"A");
                adapter.Fill(ds,"B");
                rptDoc.Load(Server.MapPath("/Report/InvoiceReport.rpt"));

                
                rptDoc.SetDataSource(ds);
                CrystalReportViewer1.ReportSource = rptDoc;
                CrystalReportViewer1.RefreshReport();

-------------------------------------------
