Also in Dinner.ascx (or DinnerForm.ascx or whatever you name it) and see if the div tag has matching id

Code:

        <div id="mapDiv">    
            <% Html.RenderPartial("Map", Model.Dinner); %>
        </div>

Ya map.ascx have the div tag with same ID "theMap"

Code:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<NerdDinner.Models.Dinner>" %>

<script src="http://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2"
 type="text/javascript"></script>

<script src="/Scripts/Map.js" type="text/javascript"></script>

<div id="theMap" style="width:520px;">
</div>
<script type="text/javascript">
   
    $(document).ready(function() {
        var latitude  = '<%:Model.Latitude.ToString().Replace(',', '.') %>';
        var longitude = '<%:Model.Longitude.ToString().Replace(',', '.') %>';
       
        if ((latitude == 0) || (longitude == 0))
            NerdDinner.LoadMap();
        else
            LoadMap(latitude, longitude, mapLoaded);
    });
      
   function mapLoaded() {
        var title = "<%: Model.Title %>";
        var address = "<%: Model.Address %>";
        LoadPin(center, title, address);
        map.SetZoomLevel(14);
    } 
      
</script>

How does it work? DinnerForm.ascx contains the mapDiv div tag. Within it, it tries to load the partial page map.ascx.

map.ascx - Another div tag here with id "theMap". The embedded javascript in map.ascx calls NerdDinner.LoadMap() (in map.js)

map.js - Load map javascript code. This is where we tell the map where to render to.

Code:

NerdDinner.MapDivId = 'theMap';

Android is unlike any other mobile development platform or Java-based environment. *Triple Bottom Line’s Android webinar *will immerse students in the Android platform, leveraging their existing Java expertise, and allowing them to walk away from the class ready to build Android GUIs and related components.On the first class you will write your first Android Activities. Through the rest of the week you will be progressively introduced to more and more of what Android has to offer – services, multitouch, and system search services. You will apply this knowledge with working code every step of the way. Be ready to work hard and learn a lot in this intensive, hands-on, five day introduction to programming with the Android platform.

Thank you sooooooooooooooooooooooooooooo much!!! I couldn't figure out why the lat/lon wouldn't save to the table.

You would think that someone would actually test the tutorials before publishing them!
