I created a 'Remember me' option on an ASP site and the client said they also wanted it to show the login name in the user field even after they press 'logout'. It works as long as I don't ever use a different login name again. Once I assign the value to the text box in the code behind, even if I manually type a new value the old value is what is used.Example:[*]I type a user/password (eg. User1), click 'Remember me' and login successfully.[*]I log out and am redirected back to the login page. On the page_load event, it detects that there is a valid cookie with the user name stored (User1) and it reads the value and sets the text field.[*]I change the login to something else (eg. User2) and it fails saying invalid user/password. Weird.[*]I check the data and it is using the old text field (User1). I try another (eg. User3) and press login. It fails and when I check the Text property, it still says User1 even though on screen it says User3.No matter what I do, it will not change once I set it in the codebehind file. It's almost as if once the text field is set, it cannot be changed. This is not right, but I have no good explanation for it.Here is the code in question
