How to disable copy and cut TextBox?

Question

On my webpage, I want to disable the copy and cut function in the context menu in the text box.

Answer 1

You can also add javascrip function to display warning

    <script language="javascript" type="text/javascript">
            function nocopy()
    {
                alert("Copying is not allowed!");
                return false;
    }
   </script>

<asp:TextBox ID="TextBox1" runat="server" oncopy="return nocopy()">  </asp:TextBox>

Answer 2

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

Answer 4

Not sure if you are looking for a way without asp, but I just found out about the cut method in JavaScript. To enter, do the following:

<input oncopy='prevent()>

<script>
function prevent()
{
 event.preventDefault();
}
</script>

It works for me. Tested on chrome. Also disables copying from the context menu. In addition, this works for the oncut and onpaste methods. However, trying to find a way for ondelete, though.

Answer 5

try it

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