How to change the login hyper link to logout when successfully logged in

[samaira]

I have created a login page when the user logs in it will take to a specified page with the text "welcome Username" and logout link on the right.but am not getting any logout link but instead itz login link which functions as a logout link though.and no message as "welcome Username"

Below is the code I have used:

<div class="loginDisplay">
  <asp:LoginView ID="HeadLoginView" runat="server" EnableViewState="false">
    <AnonymousTemplate>
      [<a href="~/Account/Login.aspx" id="HeadLoginStatus" runat="server">Log In</a>]
    </AnonymousTemplate>
    <LoggedInTemplate>
      <span>Welcome</span>
      Welcome 
      <span class="bold">
        <asp:LoginName ID="HeadLoginName" runat="server" FormatString="Welcome {0}"/>
      </span>! 
      [<asp:LoginStatus ID="HeadLoginStatus" runat="server" LogoutAction="Redirect" LogoutText="Log Out" LogoutPageUrl="~/Account/Login.aspx" />]
    </LoggedInTemplate>
  </asp:LoginView>
</div>

It sounds like the login process is not working properly.
Could you please post the server-side code that you have for when the user logs in?

[samaira]

The code I have send is in the master page.

I asked you to post the server-side code that is executed in order to log in the user. This will be the C# or the VB.NET code that authenticates the user. If you do not have this code, then that would explain why you're "login" method isn't working...and therefore the reason for why your "log-out" link is never showing up.

        }

The ASP.NET Login control works with Forms Authentication.

The code that you posted in post #6 does not use this type of authentication. So, I don't think you can use the login control.

You'll have to check session to see if your user is logged in and manually display the login or logout buttons/links accordingly (by setting their Visible property).

Hi could u plz help with how to proceed further.I was in a different domain.Recently (1.5 months bak) shifted to .net

[samaira]

I have also tried another way to create login using table control.in masterpage.cs my code is:

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

public partial class MasterPage : System.Web.UI.MasterPage
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (Session["Empname"] != null)
        {
            string ssn = Session["EmpName"].ToString();
            Label1.Text = ssn;
            btnlogout.Text = "Logout";
        }
        else
        {
            btnlogout.Text = "Login";
        }

    }
    protected void btnlogout_Click(object sender, EventArgs e)
    {
        if (Session["EmpName"] == null)
        {
            Response.Redirect("~/login.aspx");
        }
        else
        {            Response.Redirect("~/radcmbox.aspx");
        }
            }
}

[samaira]

In the above code if i login it wl take me to "radcmbox.a spx" & once i login and then on clicking logout how do i go to login page again?

[Frinavale]

It would probably be a better idea to have 2 buttons/linkbuttons instead of using 1 for two different functions.

Instead of changing the text of the one button, set the Visible property of each button.

That way you know when the user clicked the "logout" button/linkbutton and when the user clicked the "login" button/linkbutton so that you can take the appropriate action.
