if you open pop-up window using javascript by window.open funtion than in pop-up window your are not able to view address bar,menu etc so you can not click on refresh button becuase its not visible...but you can refresh page by pressing F5 key so write following block in script tag of .aspx page...

// Write following code of block in script tag like
<script type="text/javascript">

C#

document.attachEvent("onkeydown", my_onkeydown_handler);
window.history.forward(1);
document.attachEvent("onkeydown", my_onkeydown_handler);

C#

function my_onkeydown_handler() {
 switch (event.keyCode) {

      case 116: // 'F5'
          event.returnValue = false;
          event.keyCode = 0;
          window.status = "We have disabled F5";
          window.event.cancelBubble = true;
          break;
      }
  }

</script>

its solve your problem....

You're saying if you do a refresh, it shows the popup again ? I assume this means you're doing something dodgy that requires a postback to show the window ? To stop a refresh from performing the postback again, do a Response.Redirect back to the same page, so the browser goes a GET instead of a POST. But, if you do that, it will stop your code from emitting the JS that it only emits on a POST, so perhaps you just need to fix your code so it doesn't do a postback to show a popup.

If that's not what you mean, you need to explain it better.
