Step 4.The complete code of WebForm1.aspx.cs looks like this.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using SelectSPSQLQueryEntityApp.Models;

namespace SelectSPSQLQueryEntityApp
{
    public partial class WebForm1 : System.Web.UI.Page
