i've taken the employee table..
form the database.
i've added a new item crystal reports to it.. i've dragged some of the field from the dataset..

it is asking login name,servername,passward,database name..
i've not given any login name and passward to my sqlserver database what to do.. following is my code. in page load..

protected void Page_Load(object sender, EventArgs e)
    {
        ConnectionInfo cr = new ConnectionInfo();
        cr.ServerName = "VSSPL-002\\SQLEXPRESS";
        cr.DatabaseName = "employee";
        cr.UserID = "abcd";
        cr.Password = "abcd";
        string connectionSting = "Data Source=VSSPL-002\\SQLEXPRESS;Initial Catalog=employee;Integrated Security=True";

        string myQuery = "select * from employee";

        SqlConnection myConnection = new SqlConnection(connectionSting);

        SqlCommand myCommand = new SqlCommand(myQuery, myConnection);
        myCommand.Connection.Open();


        SqlDataAdapter da = new SqlDataAdapter(myCommand);
        DataSet dt = new DataSet();

        DataSet  rp = new DataSet ();
        da.Fill(dt);
        ReportDocument myrd = new ReportDocument();
        myrd.Load(@"E:\Report1\emp2\CrystalReport1.rpt");
        myrd.SetDataSource(dt);

        CrystalReportViewer1.ReportSource = myrd;
        CrystalReportViewer1.DataBind();

        //int count = Convert.ToInt32(dt.Tables[0].Rows.Count);
        myConnection.Close();
