$find returning null

I have radGrid in .ascx page in which I want to find the control using $find but it returns a null to me. Below is my code which I am using to get the object (written in .ascx).

<script type="text/javascript">
    $(function () {
        var Rates_gridID = $find('<%= gridRates.ClientID %>');
        alert(Rates_gridID);
    });
</script>

Here, I am getting Rates_gridID as null in alert. Interesting thing which I noted is when I change the jQuery version to 1.2.6 from 1.6.4 I am getting Rates_gridID object. I have googled this a lot but not getting any solution. I think the problem is with $(function().

$find is differ from $.find. The first one is provides a shortcut to the findComponent method of the Sys.Application class which defined by the Microsoft AJAX Library. while the second is API method from jQuery which get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.

So, $find has to find Component not html DOM. and ajax Library has to be defined.

If <%=gridRates.ClientID%> is unique id you should use like this

var Rates_gridID = $("#<%=gridRates.ClientID%>");
alert(Rates_gridID);

You are using the incorrect syntax. Try

$("body").find('<%= gridRates.ClientID %>');
