    </div>
<%} %>
<% else
{ %>
    <div class="col-md-3 col-4 sign-btn">
        Welcome ^__strong> <% =sLoginName %> <a href="Logout.aspx" data-toggle="modal" data-target="#userModalCenter" id="ALogout">^__i class="fa fa-sign-out"> Logout</a>
    </div>
<%} %>

Code behind:
public string sLoginName = string.Empty;

in page load:

sLoginName = Session["username"].ToString();

Sounds like you're re-inventing the wheel. ASP.NET already has perfectly good authentication and authorization systems built-in. And if you use them, you also get to use handy controls like LoginView[^] and LoginName[^], which handle a lot of the boilerplate code for you.

Check that the definition of sLoginName is part of the page class definition, not in a subsidiary class, or a general class:

public partial class MyPage: System.Web.UI.Page { public string sLoginName = string.Empty; protected void Page_Load(object sender, EventArgs e) { sLoginName = Session["username"].ToString(); } }
If that doesn't fix it, copy and paste the actual error message and related info instead of paraphrasing it.

Another option would be to define sLoginName on the page and remove it from Page_Load
C#

</form> </div> </div> <% } else { string sLoginName = Session["username"].ToString(); %> <div class="col-md-3 col-4 sign-btn"> Welcome <% =sLoginName %> <a href="Logout.aspx" data-toggle="modal" data-target="#userModalCenter" id="ALogout">class="fa fa-sign-out"> Logout</a> </div>

It may not be ideal but it can come through in a pinch

You are welcome. As I said this is not the ideal solution, just a fix for this particular page. The answer from OriginalGriff would be preferred if you are going to be working with this across multiple pages, this is more of a bandage
