You are missing '#' in jquery selector.

Hi,

You are missing '#' before the control identifiers since you are using jQuery. These are important since you are referring to the id attribute of the text/label control.

JavaScript

$("#<%= lblDisplay.ClientID %>").html($("#<%= txtDisplay.ClientID %>").val());

Thanks.

JavaScript

$(document).ready(function () {
  $('#<%=btnsubmit.ClientID %>').click(function (e) {
     $('#<%=lbldisplay.ClientID %>').text($('#<%=txtdisplay.ClientID %>').val());
//.text("value") use to set text value. of the div or span.
       e.preventDefault(); //to prevent form submission

First bug I can see is in the $(...) selector. You are trying to find an element by id, and in jQuery, this is a id selector, should be prepended with '#':
http://api.jquery.com/id-selector/[^].
