Re: [flexcoders] Re: Binding scroll position to the selected index

2006-10-12 Thread Daniel Wabyick 

Ah, that was a good idea, but it doesn't work in my case.

The list is being filtered and the selectedItem is being set via other 
code. Thus the need to bind to selectedItem, as the "change" handler 
won't be called.

I should be able to whip something up fairly easily via a subclass ...

Did you try the commitValue event?

Ok,
subclass yes.  Or, you could watch for the change of the selectedIndex
with the Observe tag.  Alex Uhlmann has a good article here:

Re: [flexcoders] Re: Binding scroll position to the selected index

2006-10-12 Thread Daniel Wabyick 

So, I got both the valueCommit and the  tag to work when 
manually setting list.selectedIndex, but not the list.selectedItem property.

You can check out either version ... For those without the  
tag, just remove those two ... They appear to be functionally equivalent 
in this case.

Re: [flexcoders] Re: Binding scroll position to the selected index

2006-10-13 Thread Daniel Wabyick 

I don't see a selectedItemChanged event ... I only see a "change" event, 
and that only gets fired when a user manually clicks and changes an item.
