UI Automation (UIA) enables accessibility applications, such as screen readers, and coded UI testing to examine user-interface elements. It also enables simulated user interaction from code. The included C1.WPF.Automation library is a set of Automation Peer classes for the ComponentOne WPF controls. Each Automation Peer exposes a matching control class to the Microsoft automation framework so the control can be used effectively in automated UI tests.

There is a free tool called Inspect.exe that enables you to inspect the current UIA tree:
