        var latlng = new google.maps.LatLng(-34.397, 150.644);
        var myOptions = {

        // use all the autocomplete options as documented at http://docs.jquery.com/Plugins/Autocomplete
        /* additional geo_autocomplete options:

        $('#<%=txtPickupCity.ClientID %>').geo_autocomplete(new google.maps.Geocoder, {
            mapkey: 'ABQIAAAAbnvDoAoYOSW2iqoXiGTpYBTIx7cuHpcaq3fYV4NM0BaZl8OxDxS9pQpgJkMv0RxjVl6cDGhDNERjaQ',
            selectFirst: false,
            minChars: 3,
            cacheLength: 50,

            scroll: true,
            scrollHeight: 330
        }).result(function(_event, _data) {
            if (_data) map.fitBounds(_data.geometry.viewport);
        });

    });
</script>
<style>
.ac_results li img {
    float: left;
    margin-right: 5px;
}
</style>

<asp:TextBox ID="txtPickupCity" runat="server" MaxLength="50" 
                                                            Width="140px"></asp:TextBox>

Thanks all i expend 4 hours on google to find out ansqwer this problem at last this is simple

on your Page_load () you use this code that will help you

 ScriptManager.RegisterStartupScript(Page, this.GetType(), "delCty", "delCity();", true);

Here "delCty" is Key "delCity()" is function name . Yes means i give function name of function

     <script type="text/javascript">
    function delCity() 
{
}

Enjoy coding . I think this will help you
