The WebBrowser control has a property called IsWebBrowserContextMenuEnabled that disables all ability to right-click

  • 0

The WebBrowser control has a property called ‘IsWebBrowserContextMenuEnabled’ that disables all ability to right-click on a web page and see a context menu. This is very close to what I want (I don’t want anyone to be able to right-click and print, hit back, hit properties, view source, etc).

The only problem is this also disables the context menu that appears in TextBoxes for copy/paste, etc.

To make this clearer, this is what I don’t want:
badcontext

This is what I do want:
goodcontext

I would like to disable the main context menu, but allow the one that appears in TextBoxes. Anyone know how I would do that? The WebBrowser.Document.ContextMenuShowing event looks promising, but doesn’t seem to properly identify the element the user is right-clicking on, either through the HtmlElementEventArgs parameter’s ‘FromElement’ and ‘ToElement’ properties, nor is the sender anything but the HtmlDocument element.

Thanks in advance!

  1. have you considered writing your own context menu in javascript? Just listen to the user right clicking on the body, then show your menu with copy and paste commands (hint: element.style.display = ‘block|none’). To copy, execute the following code:

       CopiedTxt = document.selection.createRange();    CopiedTxt.execCommand('Copy');

    And to paste:

       CopiedTxt = document.selection.createRange();    CopiedTxt.execCommand('Paste');

    NOTE: This only works in IE (which is fine for your application).

    I know its not bulletproof by any means, but here is a code sample that should get you started:

    <html>     <head>         <script type = 'text/javascript'>             var lastForm = null;             window.onload = function(){                  var menu = document.getElementById('ContextMenu');                 var cpy = document.getElementById('CopyBtn');                 var pst = document.getElementById('PasteBtn');                  document.body.onmouseup = function(){                     if (event.button == 2)                     {                         menu.style.left = event.clientX + 'px';                         menu.style.top = event.clientY + 'px';                         menu.style.display = 'block';                          return true;                     }                      menu.style.display = 'none';                 };                  cpy.onclick = function(){                     copy = document.selection.createRange();                     copy.execCommand('Copy');                     return false;                 };                  pst.onclick = function(){                     if (lastForm)                     {                         copy = lastForm.createTextRange();                         copy.execCommand('Paste');                     }                     return false;                 };             };         </script>     </head>      <body oncontextmenu = 'return false;'>         <div id = 'ContextMenu' style = 'display : none; background: #fff; border: 1px solid #aaa; position: absolute;             width : 75px;'>             <a href = '#' id = 'CopyBtn' style = 'display: block; color : blue; text-decoration: none;'>Copy</a>             <a href = '#' id = 'PasteBtn' style = 'display: block; color : blue; text-decoration: none;'>Paste</a>         </div>         sadgjghdskjghksghkds         <input type = 'text' onfocus = 'lastForm = this;' />     </body> </html>
