> For one place in our application, a ListView is used along with checkboxes, but it seems like it would be good to be able to use tri-state checkboxes here, such that a mixed state could be indicated for some entries.  But, then the question becomes:  if the checkbox is mixed, is it checked or not?  Two thoughts on that:
> 1. Add a method to get the checkbox state for all items, so you can check yourself if they are checked, unchecked or mixed.
> 2. Add a property "mixedAreChecked", which if set true (default false) would make the mixed state entries show up as checked.
> Also, how do you set the "mixed" state for an item?  Not sure about that yet.
> Altogether:  lots of implications throughout the code to support this feature.
