      if (Request.QueryString["ReturnUrl"] != null)
      {
          FormsAuthentication.RedirectFromLoginPage(userName.Text, rememberme.checked);
      }
      else
      {
          FormsAuthentication.SetAuthCookie(userName.Text, rememberme.checked);

  after successfully login, add code like this :-

  if (chkRemember.Checked)
                          {
                              HttpCookie User = new HttpCookie("UserName", email);
                              HttpCookie SBPassword = new HttpCookie("UserPassword", txtPassword.Text);
                              HttpCookie Remember = new HttpCookie("UserRemember", "True");
                              User.Expires = DateTime.Now.AddMonths(3);
                              Response.Cookies.Add(User);
                              SBPassword.Expires = DateTime.Now.AddMonths(3);
                              Response.Cookies.Add(SBPassword);
                              Remember.Expires = DateTime.Now.AddMonths(3);
                              Response.Cookies.Add(Remember);
                          }
                          else
                          {
                              HttpCookie User = new HttpCookie("UserName", "");
                              HttpCookie SBPassword = new HttpCookie("UserPassword", "");
                              HttpCookie Remember = new HttpCookie("UserRemember", "False");
                              User.Expires = DateTime.Now.AddMonths(3);
                              Response.Cookies.Add(User);
                              SBPassword.Expires = DateTime.Now.AddMonths(3);
                              Response.Cookies.Add(SBPassword);
                              Remember.Expires = DateTime.Now.AddMonths(3);
                              Response.Cookies.Add(Remember);
                          }

  how to create a remember me checkbox in the login page?

  how to add the feature to my website

  Simply drag a Login control to your page and set the DisplayRememberMe property to True

  Wildoo

  does it work like cookies?

  Yes, When using Forms authentication, ASP.NET will create a cookie (you don't need to do that yourself as suggested in other posts). When you don't use the remember me option, a Non persitant cookie is created, which will be deleted after you close the browser. When the remember me checkbox is checked, a persitant cookie is created. Both cookie have a expire time. The timespan depands on the TimeOut Property in the Forms Section on web.config, which default to 30 (minutes), so when you want to let you users be authenticated even after some days or weeks, you need to set this to a much higher value.

  Be aware that the expiry date is not updated on each and every request, but only if more than half of the Timeout interval has elapsed:

  if (chkRememberMe.Checked == true)
  {
  //Create Cookie to Store Info
  HttpCookie aCookie = new HttpCookie("Info");
  aCookie.Values["userName"] = txtUsername.Text;
  aCookie.Values["Password"] = txtPassword.Text;
  aCookie.Expires = DateTime.Now.AddDays(10);
  Response.Cookies.Add(aCookie);
  }

  hai

  <div style="margin: 0px; padding: 0px; border-width: 0px; outline-width: 0px; font-size: 13px; vertical-align: baseline; background-color: transparent;">

  You can use cookies to save user name in login controls authenticate event and populate user name text box in onload event using this cookie

  sample code for onload  

  protected void Page_Load(object sender, EventArgs e)
  
      { 
          HttpCookie cookieUserName = Request.Cookies["UserName"];
  
          if (cookieUserName != null)
  
          { 
              Login1.UserName = cookieUserName.Value; 
          } 
      }

   sample code for authenticate

  protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
      {
          Response.Cookies.Add(new HttpCookie("UserName", Login1.UserName));
      }

   thank u</div>

  hi

  The remember me option is inubuilt in login ocnbtrol, but  we need write code to work on that. To we can use the Cookies and store values and then read and can use.
  
  Here my code in easier way
  
  

  protected void LoginCtrl_LoggedIn(object sender, EventArgs e)
          {
              CheckBox rm = (CheckBox)LoginCtrl.FindControl("RememberMe");
  
              if (rm.Checked)
              {
                  HttpCookie myCookie = new HttpCookie(IMASHOPS_LOGIN);
                  Response.Cookies.Remove(IMASHOPS_LOGIN);
                  Response.Cookies.Add(myCookie);
                  myCookie.Values.Add("login", LoginCtrl.UserName.ToString());
                  myCookie.Values.Add("pass", LoginCtrl.Password.ToString());
                  DateTime dtExpiry = DateTime.Now.AddDays(15);
                  Response.Cookies[IMASHOPS_LOGIN].Expires = dtExpiry;
              }
  
              if (UserRow.RoleID == (int)eRoles.Administrator)
                  Response.Redirect("~/Default.aspx");
          }
  
          protected void btnLogOut_Click(object sender, EventArgs e)
          {
              Session.Abandon();
              HttpCookie cookie = Request.Cookies.Get(IMASHOPS_LOGIN);
              // do not use Remove method to remove cookie. also Do not use DateTime.MinValue, they do not work
              cookie.Expires = DateTime.Now.AddYears(-30);
              Response.Cookies.Add(cookie);
              Response.Redirect("~/Login.aspx");
          }
  
  My Great code here http://www.eggheadcafe.com/community/aspnet/17/10096459/login-control.aspx

  No, you don't need to write a single line of code behind. Everything can be set in web.config....
