How to Restrict Mouse Right Click on Web Page

Introduction

To make the ASP.NET web-page look-n-feel more "application-like", it is sometimes useful to restrict the right mouse click event on the page (see the working demo at www.webinfocentral.com).

Background

This project has both practical and didactic aspects. It is presented in a simple "How To" form, containing just two components:

Javascript module (rightClick.js)
Sample ASP.NET Web page (Default.aspx) to demonstrate the functionality

Using the Code

Create two files: javascript.js and Default.aspx (or any other .aspx file named up to your discretion) and place them in the ASP.NET application root directory. Copy the code snippets shown below, correspondingly.

JavaScript File

//******************************************************************************
// Module  :   rightClick.js
//******************************************************************************
// DISCLAIMER: This application is provided on AS IS basis without any warranty
//******************************************************************************
var BM = 2; // button middle
var BR = 3; // button right
var msg ="MOUSE RIGHT CLICK IS NOT SUPPORTED ON THIS PAGE";
function mouseDown(e) 
{ 
  try { if (event.button==BM||event.button==BR) {return false;} }  
  catch (e) { if (e.which == BR) {return false;} } 
}
document.oncontextmenu = function() { alert(msg); return false; }
document.onmousedown   = mouseDown;
//******************************************************************************

</html>
