    if (!IsPostBack) {
        string ConString = ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString;
        SqlConnection con = new SqlConnection(ConString);
        SqlCommand cmd = new SqlCommand();
        cmd.CommandText = "SELECT TOP 1 EmployeeID, LastName, FirstName, Title, BirthDate, City, Region, PostalCode, Country FROM Employees";
        cmd.Connection = con;
        con.Open();
        DataTable dt = new DataTable();
        dt.Load(cmd.ExecuteReader());
        if (dt.Rows.Count > 0) {
            //Bind Datatable to Labels
