I have the following code ( I have also attached a aspx file) which is very simple and has a map which initializes to the users location, and the user can choose a location from the dropdown to show on the map. The initialization works fine, but when I debug the code in firebug, I can see that geocoder.geocode is returning empty string for status. Does the call to api fail, or I am not sure what is happening. Please help. I have spent two days on this. Thanks.

Your callback doesn't do anything. The V3 Geocoder is asynchronous, so status will only be available within the callback function.
In future, best to try V3 group for JS-related questions: http://groups.google.com/group/google-maps-js-api-v3
