Hi, You can prevent using the F5 by using the following script ,and this can only be done in IE browser. if (document.all){ document.onkeydown = function (){ var key_f5 = 116; // 116 = F5 if (key_f5==event.keyCode){ alert("No refresh allowed"); return false; } } } and not sure about disabling the button in the button bars.
