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();
GridView1.DataSource = query;
GridView1.DataBind();
Label5.Text = "Records Inserted Successfully";
Label5.ForeColor = System.Drawing.Color.Green;
TextBox1.Text = string.Empty;
TextBox2.Text = string.Empty;
TextBox3.Text = string.Empty;
}
}
 #region Instance MembersCompanyEntities1 objEntities = new CompanyEntities1();
 #endregion
 }
}

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

Step 5: The output of the data inserted output operation result looks like this:
