Summary

Provides a ListBox with added functionality. See remarks.

Remarks

The extra methods ListBoxEx.RefreshItem(int) and ListBoxEx.RefreshItems() just call base methods which are inexplicably protected.

When setting SelectionMode to SelectionMode.MultiExtended, this listbox supports Ctrl+Arrow keys and Ctrl+Space properly, unlike the standard ListBox where these don’t work.
