        {
            ReportDocument crystalReport = new ReportDocument();
            crystalReport.Load(Server.MapPath("~/Report/Register.rpt"));
            DataSet1 reget = GetData("select * from Members");
            crystalReport.SetDataSource(reget);
            CrystalReportViewer1.ReportSource = crystalReport;
        }



   private DataSet1 GetData(string query)
        {
            string conString = ConfigurationManager.ConnectionStrings["ConnectionStr"].ConnectionString;
            SqlCommand cmd = new SqlCommand(query);
            using (SqlConnection con = new SqlConnection(conString))
            {
                using (SqlDataAdapter sda = new SqlDataAdapter())
                {
                    cmd.Connection = con;

                    sda.SelectCommand = cmd;
                    using (DataSet1 dsCustomers = new DataSet1())
                    {
                        sda.Fill(dsCustomers, "DataTable1");
