Shubham Choudhary 12-Apr-13 8:13am

For this you should maintain the session status every time check the session and make flag and compare if session is exist so flag will show true and when flag will show true then login button visibility going to false and and logout is true and when session is false so logout button visibility going to false and login is true

Solution 1

On click of your Login Button validate the user with database if the user is valid just write the following:-

C#

protected void btnLogin_Click(object Sender,EventArgs e)
{
//User validity check here
//you need to have two textboxtes on login page called TxtUserName,txtPassword


if((TxtUserName.Text=="Raj") && (txtPassword.Text=="password"))
{
Session["UID"]=txtUserName.Text;
Response.Redirect("HomePage.aspx");
}
}

//on page load of HomePage write the following

if(!String.IsNullOrEmpty(Session["UID"]))
{
///You need to have one label on you HomePage called lblWelcome, and one link button called ///lnkLogout. You need to set lnkLogout postbakUrl to "Loginpage.aspx".

lblWelcome.Text="Welcome" + Session["UID"].ToString();

lnkLogout.Visible=true;
}
else
{
Response.Redirect("LoginPage.aspx");
}

I guess i have given enough material to make you understand how u can use session for login status. If you have more doubts do not hesitate to ask i am always there.
