Hi calculemus,
I checked for "<divid" and that was an error on my post here. Sorry about that.

Here is my Map.ascx. I notice that pasting "div id" converts it to "divid" again. Thanks again for your help.
<%@ControlLanguage="C#"Inherits="System.Web.Mvc.ViewUserControl<NerdDinner.Models .Dinner>" %>
<scriptsrc="http://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2"

<scriptsrc="/Scripts/Map.js"type="text/javascript"></script>
<div id="theMap"style="width:520x">
</div>

<scripttype="text/javascript">

$(document).ready(function() {

var latitude = <%=Model.Latitude %>;
var longitude = <%=Model.Longitude %>;
if ((latitude == 0) || (longitude == 0))
LoadMap();
else
LoadMap(latitude, longitude, mapLoaded);

});
function mapLoaded() {

var title = "<%= Html.Encode(Model.Title) %>";
var address = "<%= Html.Encode(Model.Address) %>";
LoadPin(center, title, address);
map.SetZoomLevel(14);

}
</script>

Please don't put any more time into this. Something very weird is going on.

I thought I would use brute force to debug this thing, so I backed up my broken app and copied all the .aspx files from the download version of Views/Dinners/ into my version. Presto! it works fine.

Here is where it gets weird. I replaced the Dinners files with my old (supposedly broken) versions. It still works.

I performed the file copying etc with VS shut down.

I swear I didn't touch any other files.

I always do re-builds of the app.

I always re-start the development web server between code changes.

Any ideas?

This is a pretty scary scenario. In a real world situation, I would not have a working copy of the software to somehow "reset" the IDE.

Thank you for all of your help.

Hi taddendum,
I would do a simple diff (tortoise SVN is handy) to see if your aspx files are somehow different from the downloaded ones.

If they are somewhat the same, I suspect that it might be somehow related to your browser caching old CSS files. I highly doubt this though because you say that you're restarting your dev server after code changes.

I guess what's important is that the problem's resolved. Have fun reading rest of the book.

Good luck!

S.
