To implement this concept you need to follow the below steps :
Step1 :
First you need to design a table in Sql Database to insert the records in
database.
Step2:
Create a new Asp.net website in Visual Studio and write the following html
code in the design part of the Default.aspx page. Source code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Asp.net Insert, Edit, Update, Delete data in
Gridview</title>
<style type="text/css">
.Gridview
{
font-family:Verdana;
font-size:10pt;
font-weight:normal;
color:black;
}
.style3
{
text-decoration: none;
}
.style4
{
color: #3399FF;
}
</style>
</head>

<form id="form1" runat="server">
<div>
