I am trying to use TestStack white to test a WPF application UI automatically. One of the controls are a third party control that is composed of standard child controls, one of which is a text control that I am interested in.
I try to use the x:Name of that control to find it but getting null. I've read several articles that says custom controls are not naturally supported but a little lost when it comes to solutions.
Can anyone please suggest which direction to go? What are the options?
You're going to need to add an AutomationPeer to your new control.
