In order to accomplish this place the following java script code in between the <head> </head> tag of your master page:
<script type="text/javascript"> var message = "Sorry, Right Clicks have been disabled"; // Message for the alert box // Don't edit below! function click(e) { if (document.all) { if (event.button == 2 || event.button == 3) { alert(message); return false; } } else { if (e.button == 2 || e.button == 3) { e.preventDefault(); e.stopPropagation(); alert(message); return false; } } } if (document.all) { document.onmousedown = click; } else { document.onclick = click; } </script> P.S. Just by disabling the right click doesn't stop anyone from downloading or copying from any website as there are many other ways to do that.
