asp.net - Button click event called again when page is refreshed using F5

Question

I found that if you press F5 or refresh from browser window, the last event fires again. For ex. I have clicked on a button the button event is carried out normally, but if i press F5 from browser window then the same event is fired again.

Could someone have any idea?

Thanks for sharing your valuable time.

As per NinenthSense, thats how the browser reacts when the user refresh the page.

If you still want to restrict you can go for some javascript like below

//to avaoid pressing F5 key

document.onkeydown = function()
 {
          if(event.keyCode==116) {
          event.keyCode=0;
          event.returnValue = false;
          }
}

//to avoid refresh, using context menu of the browser

document.oncontextmenu = function() {event.returnValue = false;}
