AJAX - cascadingdropdo wn - .NET Framework

=?Utf-8?B?R2FyeSBM?=

I've implemented a cascadingdropdo wn 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

Thanks. That tells me what I need to do, just wasn't the answer I was hoping

ISSUE WITH AJAX CASCADING DROP DOWN CONTROL

by: john_mcmahon | last post by:

I'm having issues populating a second drop down menu that's dependent upon a selection in the first menu. When I select an option from the first menu, the second menu remains disabled, i.e. unable to select an option. I'm confident that most of my code is correct because of testing that I completed with it. For instance, when I remove the ParentControlID attribute from the second control and un-comment out: // string sPlantTypeID = "2";...

Ajax and IE crash

I have run into a situation that if a page/tab that uses the Ajax toolkit (using .net version 3.5) is closed before the Ajax enable controls complete loading, then IE locks up. Does it in both IE7 and IE8. There is no issue when the controls are allowed to complete loading. Can you please tell me the best practice that handles this? Thanks.
