Hi.. I want to generate crystal report in asp .net in Visual studio 2012. But it doesn't giving any error instead browser showing an empty page(No crystal report page).

Steps I have followed to generate a crystal report is as of follows:
1. Took a DataSet. Then added a DataTable. Added three columns as of my sql database table i.e. id,pname,price.
2. Took a CrystalReport.rpt and Selected Use Report Wizard. Added dataset.

using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
using System.Data;
using System.Data.SqlClient;

public partial class _Default : System.Web.UI.Page
{
    private SqlConnection cn = new SqlConnection("user id=sa;password=chiklu;database=SRS;server=CHIKLU-PC");
    protected void Page_Load(object sender, EventArgs e)
    {
        cn.Open();
        SqlCommand cmd = new SqlCommand("SELECT abcd.id,abcd.pname,qwer.price FROM abcd JOIN qwer ON abcd.id=qwer.id",cn);
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        DataSet ds = new DataSet();
        da.Fill(ds);
        ReportDocument rpd = new ReportDocument();
        rpd.Load(Server.MapPath("CrystalReport.rpt"));
        rpd.SetDatabaseLogon("sa","chiklu","CHIKLU-PC","SRS");
        rpd.SetDataSource(ds);
        CrystalReportViewer1.ReportSource = rpd;
        cn.Close();
    }
}
