Disable right click, Inspect Element and page source using JavaScript in Html and asp.net

This is a code to hide right click on any web page and to hide inspect element and page source of page.  I have used JavaScript to hide a source code below is the code. It blocks Ctrl + U , Right click , F12 , and Ctrl+ Shift + J Step One :  copy JavaScript and paste under head tag. <script> document.onkeydown = function(e) { if(event.keyCode == 123) { return false; } if(e.ctrlKey && e.shiftKey && e.keyCode == 'I'.charCodeAt(0)){ return false; } if(e.ctrlKey && e.shiftKey && e.keyCode == 'J'.charCodeAt(0)){ return false; } if(e.ctrlKey && e.keyCode == 'U'.charCodeAt(0)){ return false; } } </script> Step Two :  Put this code  in the body tag. <body oncontextmenu="return false;"> Now you can run your page and check using all the short controls and right click all are disabled now… Happy Coding Day
