In ASP.Net MVC, what is the best way to do an update from a dialog?
I'm trying to combine 2 parts of MVC that I haven't seen used together: 1) Ajax and 2) Error handling. The problem lies in what is returned and where (div element to update) that it's returned. I have an ASP.net MVC page that looks like the following <%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<Store>" %> <div id="MainPage...

I'm building a map using the google v3 api because it is way faster. Essentially, it's a map of an area with about 30 cities with polygons over the regions.
