[flexcoders] Accessing button properties from the ToggleButtonBar

[fumeng5]

Hi.

I want to set properties for each element in my ToggleButtonBar's
dataprovider, i.e. enabled, visible, etc...

Something like this:

(myToggleButtonBar.dataProvider.getItemAt(0) as Button).enabled = false;

But that doesn't work. 

I know the dataprovider of a ToggleButtonBar has to be a String,
Array, or IList. I already tried setting the dataprovider to be a
collection of buttons. 

So, is it possible to set button properties on my ToggleButtonBar?

Thanks for any tips,

fumeng.
