Fire click event on a Marker from a link

Apr 13, 2009 at 1:28 PM
Is there a way to fire the 'click' event or any marker event from something other than the marker itself?  I have a list of links outside the google map that displays information about each marker.  I would like the user to be able to click on the link and have the marker show its info window.

Hi there,

You can actually invoke the openInfoWindowHtml JS function for the required marker.
Here is a simple sample code:

<artem:GoogleMap ID="GoogleMap1" runat="server" Width="634px" Height="600px" Latitude="42.1229"

    Longitude="24.7879" Zoom="4" EnableScrollWheelZoom="true" OnClientClick="addMarker">


        <artem:GoogleMarker Latitude="42.1229" Longitude="24.7879" Title="Click on the marker"

            Text="Text of marker 1" Draggable="true">


        <artem:GoogleMarker Latitude="42.1229" Longitude="24.7879" Title="Click on the marker"

            Text="Text of marker 2" Draggable="true">





<a href="javascript:showInfoWindow(0);">Show first marker</a>

<a href="javascript:showInfoWindow(1);">Show second marker</a>


<script type="text/javascript">

    function showInfoWindow(index) {

        var marker = <%= GoogleMap1.ClientID %>.Markers[index];




Note, I'm using the marker's Text to show in the info window, but actually you can pass any HTML content there.

Hope this helps...
