Google Maps API in ASP.NET Masterpage: why it stays blank?

Question

This simple example works in pure html when launching within visual studio localhost:port server

Answer 1

Google is all Javascript, so the fact it's in a Master page shouldn't matter unless you have local path issues, which I don't see.

I would use Firefox's Error Console to see if there are any Javascript errors when the page loads.

EDIT

I thought it was some weird tag nesting issue, but it's actually the fact that you're using percentages for your dimensions. '100%' means use fill the enclosing containers space, but if the container is empty we don't get a size. If you set your map div to a fixed size, you will see your map.
