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> 

Disable cut, copy & paste using JQuery

 <script type="text/javascript">
$(document).ready(function() {
 $('#TextBox1').bind('copy paste cut',function(e) { 
 e.preventDefault(); //disable cut,copy,paste
 alert('cut,copy & paste options are disabled !!');
 });
});
</script>
 <asp:TextBox ID="TextBox1" runat="server" ></asp:TextBox>
