<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

      $("#'<%=Button1.ClientID %>'").click(function(){

    var vCheckedCBCount =  $("input:checkbox").filter(function(index){

        alert('You cannot check more than 1 check box.');
        return false;
    } 
});
 </script >
   </body>
</html>

Try this one -->

------------------------------------ASPX Code------------------------------------------------------------------------------

ASPX:

<%@ Register Src="~/UserControl/WebUserControl.ascx" TagName="ucCheckBox" TagPrefix="UC" %>

<UC:ucCheckBox ID="ucCheckBox" runat="server" />

JAVASCRIPT:

$(document).ready(function(){

    $("input:submit[id$='btnSubmit']").click(function(){

        var vCheckedCBCount =  $("input:checkbox").filter(function(index){
        return $(this)[0].checked == true;
        }).length;
        if(vCheckedCBCount > 5)
        {
            alert('You cannot check more than 5 check box.');
            return false;
        } 
    });
});

------------------------------------ASPX Code------------------------------------------------------------------------------

-------------------------------User control code--------------------------------------

UserControl:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="WebUserControl.ascx.cs" Inherits="UserControl_WebUserControl" %>
<asp:CheckBox ID="CheckBox1" runat="server" /><br />
<asp:CheckBox ID="CheckBox2" runat="server" /><br />
<asp:CheckBox ID="CheckBox3" runat="server" /><br />
<asp:CheckBox ID="CheckBox4" runat="server" /><br />
<asp:CheckBox ID="CheckBox5" runat="server" /><br />
<asp:CheckBox ID="CheckBox6" runat="server" /><br />
<asp:CheckBox ID="CheckBox7" runat="server" /><br />
<asp:CheckBox ID="CheckBox8" runat="server" /><br />
<asp:CheckBox ID="CheckBox9" runat="server" /><br />
<asp:CheckBox ID="CheckBox10" runat="server" /><br />
<asp:Button ID="btnSubmit" runat="server" Text="Continue" />

-------------------------------User control code--------------------------------------

Try

$("#'<%=Button1.ClientID %>'").click(function(){
});

A usercontrol implements INamingContainer Interface. So in order to get the elements using id you need to get the runtime generated id by using .ClientID.

When you added the usercontrol to default.aspx, the ID of Button1 changed to userControl1_Button1

So you need to change $("#Button1").click(function() so that it will always have the correct name for the button:

$("# + <%=Button1.ClientID %> +").click(function()
