Dear Reader,

I am using Google Maps for displaying Source and Destination. But I want to use AutoComplete so that it will ease user to search path easily. I am using built-in functionality of Google Maps for autocomplete. Kindly view the following function:

JavaScript

<script type="text/javascript"> 

function Initialize() {

         var autocomplete = new google.maps.places.Autocomplete('<%=TextBox1.ClientID%>');
         autocomplete.bindTo('bounds', '<%=GMap1.ClientID%>');
     }
 google.maps.event.addDomListener(window,'load',Initialize);

</script>

ASP.NET

<body>
   <form id="form1"  runat="server">
    
                    <asp:TextBox ID="TextBox1" runat="server" Width="120px"></asp:TextBox>
              
                    <cc1:GMap ID="GMap1"  runat="server" Height="240px" Width="570px" enableServerEvents="True"  />
               
   </form>
    
</body>

The AutoComplete in the above code is not working and don't know why. I have tried many google searches but unfortunately none works when I integrate with my code.

Please help me to resolve this problem by pointing out the mistake.

Please try this code:

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false&libraries=places"></script>
<script type="text/javascript">

    function Initialize() {

        var mapOptions = {
            center: new google.maps.LatLng(-33.8688, 151.2195),
            zoom: 13,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        var map = new google.maps.Map(document.getElementById('GMap1'), mapOptions);

        var input = document.getElementById('TextBox1');
        var autocomplete = new google.maps.places.Autocomplete(input);
        autocomplete.bindTo('bounds', map);

        google.maps.event.addListener(autocomplete, 'place_changed', function () {

            var place = autocomplete.getPlace();
            if (place.geometry.viewport) {
                map.fitBounds(place.geometry.viewport);
            } else {
                map.setCenter(place.geometry.location);
                map.setZoom(17);
            }
        });

    }
    google.maps.event.addDomListener(window, 'load', Initialize);

</script>

<input type="text" id="TextBox1">
        <div id="GMap1" style="height: 240px; width:570px" ></div>
