Listbox check all mode when filtered

[Jhosen]

When it's been filtered and you use the check all, it should only check or uncheck the filtered items, not all. Keeping the rest of the list unchanged.
This is very useful in long lists where we want to add or remove a subset to the selection.

In general they are going to what a code sample to verify the problem and write the unit test.
