hi all,

I have used sub reports to show some records in crystal reports. I have used dataset to fill records in crystal report. However, my main report is displaying the data but sub report is not able to display any data. I have used different datasets to fill data in sub reports as well as in main report.
I am not getting any error. Following is the code which I have to fill crystal report.


SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["DefaultConnectionString"].ConnectionString.ToString());
    SqlDataAdapter adp;
    DataSet ds;
    SqlDataAdapter adp1;
    DataSet ds1;
    DataSet ds2;
    DataSet ds3;
    string cadNo;
    string qry;
 
    protected void Page_Load(object sender, EventArgs e)
    {
        try
        {
          
            if (Request.QueryString["cadNo"] != null && Request.QueryString["cadNo"] != "")
            {
                
                cadNo = Request.QueryString["cadNo"].ToString().Trim();
                if (con.State == ConnectionState.Closed)
                {
                    con.Open();
                }
 
                qry = "select " +
                "ch.cad_number, ch.flight_number, ch.flight_date, ch.origin, ch.destination, ch.origin + '/' + ch.destination as 'origin/destination', ch.currency_code, m.mawb_number, c.commercial_code as 'Account', c.name, cd.pieces as pieces,cd.weight as weight,cd.rate as rate,cd.amount as amount, ch.amount as 'Payable To Airline' " +
