AutoCompleteBox Take TOP10 or start populating when 3 letters

Question

I have AutoCompleteBox with itemssource binding to collection. Now, in textChanged evend I'd like to populate when:

• autoComplete.Text.Length > 3 - have no idea if it possible to do this.

• take top10 results from my collection which contains autocomplete.text. This one I've tried like:

myAC.ItemsSource = myList.Where(x => x.name.Contains(myAC.Text)).Take(10);

Unfortunately, with this solution I cannot change selected item(actually when I press up/down arrow I can select only first and last item).

Thanks!

You can use MinimumPrefixLengthProperty property of autocompletebox to show results if text length >3.
