adding crystal report via code

[HunainHafeez]

i successfully designed and filled my Crystal report via code not via wizard.

i added Crystal report via addNEWITEM
i added dataset in aap_code via addNEWITEM
i added datatable into dataset via addNEWITEM
Via code i made report and filled dataset and table with data
Run and display. Successfully done.
but my question is that how to do it fully via code like for steps 1,2,3 ? I don't want to add it via AddNewItem etc, isn't there any way to add these via code ? i did, i created some datasets and table via code like we do for Gridview etc but that doesn't appear in DATA connections of crystal report etc.

String conStr =WebConfigurationManager.ConnectionStrings["LoginDatabaseConnectionString"].ConnectionString;

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack) 
    {
        Dataset_load();
    }
}

protected void Dataset_load() 
{
    SqlConnection sqlcon = new SqlConnection(conStr);
    SqlCommand sqlCom = new SqlCommand("select * from Login", sqlcon);
    SqlDataAdapter sqlDA = new SqlDataAdapter(sqlCom);
   // DataSet ds = new DataSet("CRDataSet");

    try
    {
        sqlcon.Open();
        //sqlCom.ExecuteNonQuery();
        //sqlDA.Fill(ds,"Login");

        DataSet1 ds = new DataSet1();
        DataTable dt = new DataTable("DT_CR");
        sqlDA.Fill(dt);
        ds.Tables[0].Merge(dt);

        ReportDocument rd = new ReportDocument();
        rd.Load(Server.MapPath("CrystalReport.rpt"));
        rd.SetDataSource(ds);
        CrystalReportViewer1.ReportSource = rd;


    }
    catch (Exception exc)
    {
        Response.Write(exc.Message);
    }
    finally 
    {
        sqlcon.Close();
    }
