I'm building a reusable controls library for my company and have been using the WPF Toolkit as a model to follow for how to organise folders, theme styles, etc. One point I'm confused on is why certain control classes in the WPF Toolkit, such as Calendar
and DatePicker -- are declared as partial? For example:
public partial class DatePicker : Control
public partial class Calendar : Control
These are not user controls, meaning they don't have a code-behind file, so what's the point?
