Hi,
I also just started learning ASP.NET AJAX for real and I wanted to check out the Samples that one can download. I thought using the SimpleList would be the easiest but I soon found out that when you want to run the DragOverlayExtender began complaining. Seemed the web.config isn't complete. I added these extra lines in order to get it to work:
<profile>
<properties>
<add name="dragOverlayPosition"/>
</properties>
</profile>
and
<profileService enabled="true"
readAccessProperties="dragOverlayPosition"
writeAccessProperties="dragOverlayPosition" />
I hope this helps other people out that are just starting to play around with the samples
If you like to read more about it...
Grz, Kris.
