<script type="text/javascript">
        var message = "Right Click Disabled!";
        function DisableIE() {
            if (event.button == 2) { alert(message); return false; }
        }
        function DisableOther(e) {
            if (document.layers || document.getElementById && !document.all)
            { if (e.which == 2 || e.which == 3) { alert(message); return false; } }
        }
        if (document.layers) { document.captureEvents(Event.MOUSEDOWN); document.onmousedown = DisableOther; }
        else if (document.all && !document.getElementById) { document.onmousedown = DisableIE; }
        document.oncontextmenu = new Function("alert(message);return false")

        <add tagPrefix="uc2" src="~/usercontrols/Address2.ascx" tagName="Address2"/>
      </controls>
    </pages>
  </system.web>
</configuration>
