How to show message to user when page is in a filtered state? I have a view with a few exposed filters and it uses ajax. It is set to remember their last selection. Is there any way to ensure that the user is aware the the view still has applied filters? (i.e. Some users may not be ware that the list is still filtered and they need to hit the reset button).

Edit

To further clarify:

The issue is that if the user is not aware that the list is in a filtered state that they should reset it before starting another drill down

Basically I need it to say "Hey you! this list is in a filtered state. You need to hit the reset button before doing another search!"
In views, to remember the user entry, Views uses sessions. It uses different variables for each view. If you print the $_SESSION variable you can see that. 

function MODULENAME_form_alter(&amp;$form, &amp;$form_state, $form_id) {
  if ($form['#id'] == 'views-exposed-form-test-page'){ //your exposed form's id

      print_r($_SESSION);
   }
}


Now you can see that a structure like below

[views] =&amp;gt; Array
    (
        [test] =&amp;gt; Array
            (
                [default] =&amp;gt; Array
                    (
                        [title] =&amp;gt; Page
                    )

            )

    )


So if you check value exists for this variable,  you can perform your task

ie: 

if ($form['#id'] == 'views-exposed-form-test-page'){
//check is it exists, if so perform your task
 if($_SESSION['views']['test']['default']['title'] != ''){
    // "need to reset";
          //here using jquery or css, show or hide your message
        $script="(function ($) {
                //action to do here
        })(jQuery);";
        drupal_add_js($script,'inline');
 }
}


Hope this may helps you
