Autocomplete control suggestion popup refresh

Let’s say I use the following IAutocompleteSource implementation :

    public class TestClass : IAutocompleteSource
    {
        public ObservableCollection<Image> ItemsLst { get; set; }
        public IEnumerable Search(string searchTerm)
        {
            searchTerm = searchTerm ?? string.Empty;
            searchTerm = searchTerm.ToLower();

            return ItemsLst.Where(item => item.imgName.ToLower().Contains(searchTerm));
        }
    }

If later on, ItemLst content changes, it will not get reflected directly in the Autocomplete suggestion popup until something new is typed (which triggers the Search() method, I imagine, and refresh the IEnumerable).

@Coloris This commit introduces the IAutocompleteSourceChangingItems interface and AutocompleteSourceChangingItems as an abstract implementation.

Derive your autocomplete source from AutocompleteSourceChangingItems and call the OnAutocompleteSourceItemsChanged() method, if the list changes. Then the Autocomplete will trigger a new search with the recent search term to get a new list of items.

I am planning to put it in a release next week.

Same situation also for me. I tried the AutocompleteSourceItemsChanged but it doesn’t work. The @infirazor 's trick works but it is a little “dirty”…
