      you could clear the text boxes using java script
      Code:
      function myfunction()
{

document.getElementById('TextBox1').value="";


}
<body onload="myFunction()">

          You could also disable ViewState for the user id TextBox.
          It will not retain it's values then.

          Also, you could clear the text boxes in your server code (in the PreRender event):
          Code:
             myUserIdTextBox.Text = ""
   myPassword.Text = ""
          Your password field should not keep it's value though, usually this clears automatically if you have indicated that the TextBox is for a password.

                      As you've noticed, this is an issue specific to Netscape/Gecko-based browsers. When you clear the cache from the Tools menu then the issue is resolved. But by default this occurs as a result of the built-in feature called Form and Password Auto-completion.

                      The suggested solutions given are good, although it seems like a strange function to have to implement. Alternatively, a more precise method is to use the autocomplete attribute in either your FORM element or to each individual INPUT element:

                      Code:
                       
<form autocomplete="off">
</form>

OR

<input type="text" autocomplete="off" />
                      You can read more about it here:
                      http://devedge-temp.mozilla.org/viewsource/2003/form-autocompletion/index_en.html


                      Can I ask why it's imperative that you have your login page this way?

                              Hi :)
                              Welcome to Bytes.

                              When you hit the back button, the browser displays a version of the page that it cached. Your server-side code cannot detect this and so you cannot use C# or VB.NET code to clear the data.

                              You can try using meta tags to indicate that the page has expired (as soon as it's sent) and to indicate that no caching should happen. But meta tags are just suggestions and they don't work in all browsers.

                              The best solution that I have found is to place all of your page controls into an UpdatePanel. This will result in asynchronous postbacks to the server and the browser cannot cache this. So, when the user hits the back button, the page that is displayed is the version of the page that was sent to the browser during the first page request.
