Remarks
This property is the UI Automation provider for the window of a custom control. UI Automation uses this provider in combination with your provider implementation for a control hosted in a window. For example, the run-time identifier of the element is obtained from the host provider.
A host provider must be returned in any of the following cases:
This element is the root of a fragment.
The element is a simple element such as a pushbutton.
The provider is a repositioning placeholder.
In other cases, the property should return null
.
