AJAX - cascadingdropdown

I've implemented a cascadingdropdown modeling the examples found on the web
and that work fine on an initial data entry screen. What I can't seem to
find an example of is after I've stored data and want to come back to the
screen for editing how can I get the lists to populate and set the
appropriate value? Any examples out there that I'm just not finding?

Thanks!

Mmmm...

Maybe I'm wrong or I'm missing something, but some weeks ago I face a
similar problem, and it seems that cascading drop down is not prepared for
"update mode".

Possible solutions:

- Implement the out of bounds calls simulating that a client is selecting
the right option (you should first place a javascript method to be fired when
the page is loaded on the browser, and then go capturing the outofbound
calls).

- Extend the Toolkit control to allow "update mode".

- Use another login for the cascading (build up your own methods to
update, maybe via webservices, or altough is not very optimal, using update
panels).

If somebody knows a better solution, please giveme a shout :-)

Good luck
