Is there an implementation/example of the Windows Phone native search in the People hup ? (shows a ListBox and typing in the SearchBox will filter the people in the list, and highlighting the matching texts). I was especially looking for a modification of the Windows Phone Toolkit AutocompleteBox.
If nothing exists already, what would I need to do to mix the Toolkit LongListSelector with AutoCompleteBox (replacing the autocomplete popup with a filtering of a list) ?
I haven't seen anything, because it's so easy to implement. As for implementing it with the LongListSelector and a AutoCompleteBox, you should simply use either a CollectionViewSource or having a original, and filtered, data source, where the active displays the filtered items.
