Thanks Kenneth, finally I could fix it.
The problem was that style for the "map" div is not being placed suitable
and thus the map was not displayed.
It happenned because my aspx page had the XHTML doc type at start of the
page.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
XHTML hopes that the styles to be linked to other CSS file. So I removed
this line and the example is working.
