WPF semi cascading listbox

I have 3 controls on my page

  • ListBox A
  • ListBox B
  • ComboBox C

ListBox A is databound to a collection of items A

ComboBox C is databound to a collection of items C

ListBox B is databound to a collection of items B

B has a reference to Item A and Item C, the ListBox B should only show the items where Item A is the selected item of ListBox A, and Item C is the selected item of ListBox C

i've messed a little with collectionviews as ItemSource on ListBox B, setting a filter, but I can only get it to update the content of ListBox B based on either ListBox A or ComboBox C, not them both at the same time.

Any ideas?
