hi,

In my ASP.NET application. I have used JQuery Autocomplete for retrieving database values using Handlers(.ashx).

Now the problem is, i used "UpdatePanel" to avoid flickering on Postback. Now those Autocomplete textbox are lost its JQuery reference on each Postback hence i need to rebind those textbox with the corresponding JQuery reference(From my previous post i got it from an developer).

Reference : How to Enable JQuery Autocomplete textbox inside Gridview with UpdatePanel?[^] [^]


Hence i used the code

<script type="text/javascript">

    $(function () //Object Expected Error here
    {
        initializer();
    });

    var prmInstance = Sys.WebForms.PageRequestManager.getInstance(); //"Undefined variable Sys" error here

    prmInstance.add_endRequest(function () { //"Null reference" error here
        //you need to re-bind your jquery events here
        initializer();
    });

    function initializer()
    {
        $("#<%=txtProductName.ClientID%>").autocomplete('Products.ashx');
    }
</script>

From the reference : http://forums.asp.net/p/1622254/4164277.aspx[^]

But i'm getting error "Object Expected" in very first line.

I'm beginner in JQuery.

Any help would be appreciated.
