virtual earth - Only map is not rendering

Question

I am facing this strange issue. The bing map does not display on my page where as all the controls even pushpins displays properly.
I googled a lot and same the functionality is working great in my other project(s)

I suspect that something is wrong with the reference to the dev.virtualearth.net, Or I am missing something

Here is my code: ASCX (is inside the content place holder of dynamically generated aspx):

<script charset="UTF-8" type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2&mkt=de-de">
</script>

<div>
       .
       .
       .
       <div id="bigMapContainer">
                <div id="eventMap">
                </div>
       </div>

</div>

Code behind:

string script = @"
            function GetVEMap() {
               map = new VEMap('eventMap');
               map.SetDashboardSize(VEDashboardSize.Small);
               map.LoadMap();
               DisplayEventsOnMap();
            }

   function DisplayEventsOnMap() {
                var eventMapLayer = new VEShapeLayer();
                eventMapLayer.Id = 'eventMapLayer';
                var points = null;
                       .
                       .
                       .
                //Code to get the data for pin display etc
                       .
                       .
               map.AddShapeLayer(eventMapLayer);
               map.SetMapView(eventMapLayer.GetBoundingRectangle());
               map.SetZoomLevel(15);

              });
            }

            $(window).load(function() {
                       GetVEMap();
                      }
            );";

     ScriptManager.RegisterStartupScript(this, typeof(Page), "MapDisplay", script, true);

CSS:

   #bigMapContainer {display: block;}
   #eventMap { position: absolute; width: 550px height: 500px; }

I have added some references on the master pages which are not related to the map but might conflict with my map implementation(?)

<script type="text/javascript" src="/js/modernizr-2.0.6.min.js"></script>
<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.8.2.min.js"></script>

<script type="text/javascript" src="/js/jquery.responsivemenu.js"></script>
<script type="text/javascript" src="/js/client.js"></script>
<script type="text/javascript" src="/js/jquery-ui.js"></script>

Help is very much appreciated.

Answer 1

After a huge reserach I found that the issue was with the css. Thanks @rbrunditt for help

mapcontrol.css inside http://ecn.dev.virtualearth.net/mapcontrol/v6.3/css/bin/6.3.20091207154938.04/de/mapcontrol.css have a class for the map container- .MSVE_Map which have the attribute position:absolute which was making the tiles display out of the screen.

I have overridden the class to position:relative which actually solved the issue..
