Hi Nandakumar,

Once you are click on Login button. After user login successfully you can store your user name in session like below,
Session["UserName"] = UserNameTextBox.Text;
After this when ever you want to use your username in current user login you can retrive username like below,
if(Session["UserName"] != null)
{
string userName = Session["UserName"].ToString();

}

Hi Nandhakumar Nagarajan,

The following code is used for storing a value to the session.
Session["username"] = txtUser.Text;
Note :

In most cases, sessions are tracked with cookies. So using your example, when the user object is saved to Session. If you want information shared between different clients from the web server, use Cache.

Hi Nagarajan,

You Can store Data into session like this,
Session["Name"] = txtname.Text;
And Retrive Data from Session like as:
if(Session["Name"]!=null)
{
txtname.Text=Session["Name"].tostring();
}

Hi Nandhakumar,

go through below code

HTML
<table border="0" cellpadding="0" cellspacing="0">
<tr>
<td>
User Name
td>
<td>
<asp:TextBox ID="txtName" runat="server" />
td>
tr>
<tr>
<td>
Password
td>
<td>
<asp:TextBox ID="txtPassword" runat="server" />
td>
tr>
<tr>
<td>
<asp:Button Text="Login" runat="server" OnClick="LogIn" />
td>
tr>
table>
C# Code
protected void LogIn(object sender, EventArgs e)
{
bool valid = false;
//Validate Name and Password with database.
if (txtName.Text.Trim().ToLower() == "sa" && txtPassword.Text.Trim().ToLower() == "sa")
{
valid = true;
}
if (valid)
{
//Create a Cookie with a suitable Key.
HttpCookie loginCookie = new HttpCookie("Login");
//Set the Cookie value.
loginCookie.Values["Name"] = txtName.Text;
loginCookie.Values["Password"] = txtPassword.Text;
loginCookie.Path = Request.ApplicationPath;
//Set the Expiry date.
loginCookie.Expires = DateTime.Now.AddDays(1);
//Add the Cookie to Browser.
Response.Cookies.Add(loginCookie);
Response.Redirect("Home.aspx");
}
else
{
Response.Redirect("Login.aspx");
}
}
You need to write the below code in your MasterPage. If you don't have master page then you need to write the code in each page for checking the validation with database record.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
HttpCookie loginCookie = Request.Cookies["Login"];
if (loginCookie != null)
{
string name = loginCookie.Values["Name"];
string password = loginCookie.Values["Password"];
// User validation based on cookies if required for valid user as might be user can change his password in any cases
// so call your databse user login validation method
if (name.ToLower() == "sa" && password.ToLower() == "sa") // user validation code
{
Response.Redirect("Home.aspx");
}
else
{
Response.Redirect("Login.aspx");
}
}
}
}
Note: Here i have hardcoded the value. So you need to change as per your requirement.
