Disable cut, copy and paste in textbox using jquery, javascript

Due to some reasons (like don’t allow to copy Email from Email TextBox to Confirm Email TextBox), we restrict users to copy, paste and cut contents from TextBox by using CTRL+C, CTRL+V and CTRL+X. We can implement this functionality by using below methods.

Disable cut, copy & paste using Javascript

1. When we don't want to display any message on cut, copy & paste

    <asp:TextBox ID="TextBox1" runat="server" oncopy="return false" onpaste="return false" oncut="return false"></asp:TextBox> 

2. When we want to display an alert message on copy, paste and cut

    <script language="javascript" type="text/javascript">
   function DisableCopyPaste (e) 
   {
    // Message to display
    var message = "Cntrl key/ Right Click Option disabled";
    // check mouse right click or Ctrl key press
   var kCode = event.keyCode || e.charCode; 
   //FF and Safari use e.charCode, while IE use e.keyCode
    if (kCode == 17 || kCode == 2)
    {
    alert(message);
    return false;
    }
   }
   </script>
    <asp:TextBox ID="TextBox1" runat="server" onKeyDown="return DisableCopyPaste(event)"onMouseDown="return DisableCopyPaste (event)"></asp:TextBox>
