  to create Session:

  Session["User"] = "user1";

  to retrieve session:

  string user = (string)Session["User"];

  to end session:

  Session.Abandon();

  Thank you Patrik ! But how I do this when I click on EXIT  ? something like this: I know that i may use href="#" to redirect to another page, is that right ? But how I end the session as well and get back to the login page ? Thanks

  <ul id = "list">
  
    <li>Exit</li>
  
  </ul>

  yes you can do that this way,

  <li><asp:LinkButton OnClick="lnkExit_Click" runat="Server" Text="Exit"></asp:LinkButton></li>

  and in aspx.cs write this code,

  protected void lnkExit_Click(object sender, EventArgs e)
  {
  Session.Abandon();
  Response.Redirect("Login.aspx");
  }

  {
  Session.Abandon();
  Response.Redirect("Login.aspx");
  }

  So I HAVE TO add a button on my <li></li> ? Because I was using just the link of <li> like this:

  

  <ul class="leftnav">
  
                       <li><a href="#">Usuários</a>
                          <ul class="submenu">
                              <li><a href="/CadastraUsuario.aspx">Cadastrar Usuário</a></li>
                              <li><a href="#">Alterar Usuário</a></li>
                              <li><a href="#">Apagar Usuário</a></li>                        
                          </ul>
                       </li>
  
                       <li><a href="#">Minhas Tarefas</a>
                          <ul class="submenu">
                              <li><a href="#">Chamados</a></li>
                              <li><a href="#">Chamados em Aberto</a></li>
                              <li><a href="#">Finalizados</a></li>                        
                          </ul>
                       </li>
  
                       <li><a href="#">Clubes/Projetos</a>
                          <ul class="submenu">
                              <li><a href="#">Inserir Clube</a></li>
                              <li><a href="#">Alterar Clube</a></li>
                              <li><a href="#">Apagar Clube</a></li>                        
                          </ul>
                      </li>
  
                       <li><a href="#">Chamados</a>
                          <ul class="submenu">
                              <li><a href="#">Cadastrar Novo Chamado</a></li>
                              <li><a href="#">Manipular</a></li>
                              <li><a href="#">Atividades</a></li>                            
                          
                          </ul>
                       </li>

  yes dear if you want to do anything at server side(like end session here) then you have to do like that..because using only <li><a></a></li> will not end your session, it will jst take you to the other page.

  Got it ! Thanks a lot ! 

  Just one more thing, what If in the <li><a></a></li> I redirect to the log in page and in the Page_Load of login.aspx i used

  protected void Page_Load( . ..
  {
    Session.RemoveAll();
  }

  Would it work ?

  that is the same thing too..but understand one risk..If anyone click on logout/exit link and suddenly he/she closes the browser before even your login.aspx page opens, what will be the result?? he/she will remain logged in..so better thing would be, first end the session and then redirect..otherwise both are the same thing.

  True.. You're right  Thanks again Patrik, for keeping helping me xD . Gee, im so noob ;s 

  One more thing and i'll stop bothering you, I promese ! 

  I just need a little 'push' to get start and i can do the rest on my own. I'm getting a little difficult to start thsi sessions thing

  -I have my log in page, I make a SELECT in the DataBase to see if the login/password match. I Know that if its right I have to begin the session.

  Session["Login"] = TxtLogin.ToString();

  But what then ? I don't know what to do next... Other thing is, if I type the path for a page, it gets in the page normally, without needing login.. Could you help me to fix it ? Or just show me the way. I'm not lazy, I'm searching in google a lot, but nothing worked so far. And I need this to my job, im at it right know =P

  Thanks again Patrik ! You're a great guy !
