 Step 2: The complete code of webform1.aspx looks like this:

 Step 3: 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;
 namespace
InsertSPLINQApp
 {
     public partial class WebForm1 : System.Web.UI.Page
     {
         protected void Page_Load(object sender, EventArgs e)
         {
         }
         protected void Button1_Click(object sender, EventArgs e)
         {
             if(string.IsNullOrEmpty(TextBox1.Text)||string.IsNullOrEmpty(TextBox2.Text)||
                 string.IsNullOrEmpty(TextBox3.Text))
             {
                 Label5.Text = "Please Enter Some Values";
                 Label5.ForeColor = System.Drawing.Color.Red;
             }
            
else
 
            {
                 objEntities.InsertEmployeeData(TextBox1.Text, TextBox2.Text,
                     int.Parse(TextBox3.Text));
                 var query = objEntities.SelectEmpData();

 Step 4: The output of the application looks like this:
