553797 Integrate Google Maps with existing asp.net + XML page

Hi, I have a page (or pages) that makes an XML over HTTP request for details of a number of building locations and then binds that data to a datagrid. The data includes name, a corresponding hyperlink and x/y co-ordinates. I would like to extend the page so that as well as binding the data to a datagrid, it also draws a Google Map and adds markers for each location. The markers will invoke a bubble with the name and the corresponding hyperlink. The page is asp.net based, using VB.net. It doesn't use code behind so all the coding is in the page itself.
