Answer 1

You can make the ItemsSource as MultiBinding to be binded to the list and the textbox, and in the converter go over the list, and hide items you don't want (according to the textbox).

Not a too nice solution, but it should work.

This is the multibinding:

And in the convert method run with foreach on the parnetlist, and conditions that if the ListItem equals the text, it should be collapsed.
