Access Session Value at Client Side Using JavaScript In Asp.Net

8/04/2014 - By Pranav Singh 0

This article will show you how you can access the session value at client end using JavaScript. In this article I will provide a trick to access the session value using JavaScript in your asp.net application.


So for this article first we will create a new asp.net application and add the below code into your ..cs page

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

namespace ProjectDemo_Asp.et
{
    public partial class Session : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Session["UserDemo"] = "This is demo.";
        }
    }
}

In above code I am storing some value in session which I am going to access this value in my JavaScript. Now we check the .aspx code.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Session.aspx.cs" Inherits="ProjectDemo_Asp.et.Session" %>

<!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>Access Session Value at Client Side Using JavaScript In Asp.Net</title>
    <script language="javascript" type="text/javascript">
        function GetSessionValue() {
            alert("Session Value : " + document.getElementById("txtvalue").value);
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <input type="text" id="valuetodisplay" value="<%=Session["UserDemo"] %>" />
        <input type="hidden" id="txtvalue" value="<%=Session["UserDemo"] %>" />
        <br />
        <br />       
    </div>
    </form>
    <script language="javascript" type="text/javascript">
        GetSessionValue();
    </script>
</body>
</html>

In above code I have stored the session value into hidden field and then I am accessing the hidden field value by using JavaScript. Here is the output.


Now click on ok button to check the textbox value. I have shown the value in textbox also just for demonstration.
