[mapguide-users] POOL:DWF or AJAX

[Andrew DeMerchant]

I can certainly vouch for that....for me, ODBC is pretty much useless in 
AJAX because of the horrible speed. I had a few hundred points.....it's 
still slow in DWF if you do things like filters and/or themed layers., 
but it's at least useable.

As for the OnSelect question, I have no idea. I'm not doing anything 
like that....though, I may at some point, I have no need just yet.
