In this article I provide a quick overview of how to insert a record into SQL Server using jQuery. You can do it many ways such as using Generic Handlers and using a WCF service. Here you will see it using Generic Handlers in ASP.Net. First we create a database table named "Test".
Creating SQL Database Table
This database contains one table named test.
CREATE TABLE [dbo].[Test](
[Name] [varchar](50) NULL,
[Email] [varchar](100) NULL
)
Now press F5 to execute the script above that looks like this:

ASP.NET Handler
Right-click your ASP.NET Project then select "Add New Item" -> "Generic Handler" and give it the name "Test.ashx".

The default handler (ashx) file code looks like this:
<%@ WebHandler Language="C#" Class="Test" %>
using System;
using System.Web;
public class Handler : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
context.Response.Write("Hello World");
}
public bool IsReusable {
get {
return false;
}
}
}
Now create a .cs class file in the application and provide the same name as in:
Class="Test"
Now use "CTRL+X" and the following code from the code above.
using System;
using System.Web;
public class Handler : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
context.Response.Write("Hello World");
}
public bool IsReusable {
get {
return false;
}
}
}
Now paste it into the .cv file. The code in the file will look like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data;
using System.Data.SqlClient;
public class Test : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
if (HttpContext.Current.Request.QueryString["StrMethod"].ToUpper() == "SAVE")
{
Connection();
}
}
public bool IsReusable
{
get
{
return false;
}
}
public string Connection()
{
SqlConnection con = new SqlConnection(@"Data Source=.; Database=Test; User ID=sa;Password=Micr0s0ft");
con.Open();
SqlCommand cmd = new SqlCommand("Insert into Test values('" + HttpContext.Current.Request.Form["UserName"] + "', '" + HttpContext.Current.Request.Form["Email"] + "')", con);
cmd.ExecuteNonQuery();
return "True";
}
}
.ASPX Page
Right-click your ASP.NET Project then select "Add New Item" -> "New Page" and give it the name "Test.aspx" and add the following control into it:
![page-in-asp-net.jpg]()
Now click on the source tab and add the following code:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ClientID.aspx.cs" Inherits="ClientID" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#Button1').click(function () {
var strMethod = "SAVE";
var StrUrl = 'Test.ashx?StrMethod=' + strMethod;
$.ajax({
type: 'POST',
url: StrUrl,
data: {
UserName: $('#txtUserName').val(),
Email: $('#txtEmail').val()
},
async: false,
success: function (response) {
$('#txtUserName').val('');
$('#txtEmail').val('');
alert("Record Has been Saved in Database");
}
});
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<br />
<br />
UserName:
<asp:TextBox ID="txtUserName" runat="server" ClientIDMode="Static" Width="202px"></asp:TextBox>
<br />
<br />
Email:
<asp:TextBox ID="txtEmail" runat="server" ClientIDMode="Static" Width="210px"></asp:TextBox>
<br />
<br />
<asp:Button ID="Button1" runat="server" Text="Button" />
</div>
</form>
</body>
</html>
Now Run the application.

Now enter the name and email into the corresponding TextBox.
![name-and-email-in-asp-net.jpg]()
Now click on the Button control.

Now open the SQL Server database and check it.
