you need to learn use of Session variables. you need to persist your username though out the active session.

Solution 1

C#

WindowsPrincipal principal = (WindowsPrincipal)Thread.CurrentPrincipal;
// or, if you're in Asp.Net with windows authentication you can use:
// WindowsPrincipal principal = (WindowsPrincipal)User;
using (PrincipalContext pc = new PrincipalContext(ContextType.Domain))
{
    UserPrincipal up = UserPrincipal.FindByIdentity(pc, principal.Identity.Name);
    return up.DisplayName;
    // or return up.GivenName + " " + up.Surname;
}

Simple way is use session.

create session for username
for ex: session["UserName"]

you can also create multiple session, and use in all page of current project.

accept if ans. is right.
