Created Issue: multiselectlist ItemContainerGenerator [9824]

Hi,

I'm having a problem with the multiselectlist control. I suspect not a bug but a lack of my understanding.

I'm trying to set up the list with items previously selected.

when using the line:

MultiselectItem container = target.ItemContainerGenerator.ContainerFromIndex(i) as MultiselectItem;

this returns null after in index 15 - yet there are 28 items in my list.

Thanks in advance
