  Windows Authentication box when Session Expires

  Sep 01, 2016 01:27 PM|hanspam|LINK

  Im working on a project with Windows Authentication and Session States.

  I have this code where i get the username, save it in a session and also in a label

  if (!IsPostBack)
  {
      using (var context = new PrincipalContext(ContextType.Domain))
      {
          var usr = UserPrincipal.FindByIdentity(context, User.Identity.Name);
          if (usr != null)
              Session["Application1_Data"] = usr.DisplayName;
              lbl_Login.Text = usr.DisplayName;
      }
  }
  
  

  After this I have the other pages where I receive the data of my session like this

  if (Session["Application1_Data"] != null)
  {
      lbl_Login.Text = Session["Application1_Data"].ToString();
  }
  else
  {
      Response.Redirect("Index.aspx");
  }

  If the session expires I made a redirect to the index page where I define the session but I want to remain on the same page,

  How do I show a authentication box to enter windows credentials? instead of going back to the first page and starting afresh

  change this line of code to do what ever you want....

  Response.Redirect("Index.aspx");

  you could popup a login box to have the user re-authenticate.

  There a few ways to deal with this
