Hi alhakimyyes,

Check the below example.

HTML

<asp:TextBox ID="txtId" runat="server"></asp:TextBox>
<script type="text/javascript">
    window.onload = function () {
        var txt = document.getElementById('<%=txtId.ClientID%>');
        txt.setAttribute("autocomplete", "off");
        txt.setAttribute("onkeypress", "KeyPress(event)");
        txt.setAttribute("onpaste", "Paste(event)");
    }
    function KeyPress(e) {
        alert('key pressed');
    }
    function Paste(e) {
        e.preventDefault();
    }
</script>
