Hello All,

I'm wondering if anyone has had any luck rendering a map inside a
master page.  I am getting the typical error: Internet Explorer cannot
open the Internet Site [url] operation aborted.  I see the map rendered
on the page underneath the error.  I'm calling the JavaScript in the
ClientScript.RegisterStartupScript(//the javascript code) method.  This
will generate the call to the script on window.onload.  I'm thinking
that since my master page puts my content box within a table that this
is causing the problem.  Is it possible to render a map within content
place holder in a table on a master page?  Any insights would be
appreciated.

Thanks,
Mark

I also tried putting the content holder outside the table and still had
no success.  I am using the RegisterStartupScript method because I have
to query a database to get my lats and longs.

Thanks again.

I have made a .NET control which works under the circumstances you
describe. Try it at http://www.reimers.dk/

Your wrapper is awesome.  Really good work.  I'm definitely going to
use it.  I would still like to know why this problem was occurring even
though it's a non issue now because of your control.  Maybe it would've
worked if I added a timeout option....I don't know.  Thank you so much
for your help.

Glad you like the control. The problem with IE is that it doesn't like
it when you change the contents of DOM elements before the page is done
loading. Now people hate IE because it complies with the standards :-)

There are some workarounds.
The most popular is to run the map rendering code from the page body's
load event. This is somewhat bothersome when working with masterpages.
Another way is making a script block that uses the defer attribute, but
this is not guaranteed to work cross-browser.
Finally you can delay running the script manually by using a timeout,
but this sometimes causes trouble with very busy pages.

As you can see there is not a golden solution when working with master
pages as you don't have the possibility to write in the master file's
markup. So you have to do it programatically or use options 2 or 3.

Thanks again.  I had the map working using ajax very nicely passing
back my lats and longs in an xml string and then using the xmlDom
object to parse it in javascript and render the map.  My user wanted
the browsers back and forward buttons to bring back the previous map
image, though....which brought me to this problem.  I really appreciate
your help.

The real answer is to declare your geoinformation as a a function

For Example
---------------------------------

Function mapthis(){
Map stuff here

------------------------------------

Then declare your function on the body load like this.

------------------------------------
onload="mapthis()"
------------------------------------

Make sure you put the includes javascript component in the body of the
page at the bottom.

Why? The reason your map dosnt work is because it launches before all
the googlemaps calls have been made. by creating a function to incase
your code in, you force the browser to load all external page
content(ie google maps api) before lauching your personalized codes.

Thanks!  The ClientScript.RegisterStartupScript(//the javascript code)
places the call to the JavaScript below the html in the body and calls
it during the window.onload method.  I actually already have my
javascript in another function and file.   I was using the
RegisterStartupScript function to pass xml back to the client that
contained my lats, longs, and styles for icons on my map.  I guess I
could do a bunch of inline vbscript on the page to get at some server
variables, but I wanted a more elegant solution.
