Documentation

IToggleProvider documentation: https://learn.microsoft.com/en-us/windows/win32/api/uiautomationcore/nn-uiautomationcore-itoggleprovider

Behavior

Components of control type CheckBox must implement the IToggleProvider. Components of control type Button, ListItem, MenuItem, and TreeItem should conditionally implement the IToggleProvider (See Documentation: https://learn.microsoft.com/en-us/windows/win32/winauto/uiauto-controlpatternmapping). The toggle state of the control should be used as input for the IToggleProvider data.

Implementation Plan

We should:

Implement the IToggleProvider APIs in CompositionDynamicAutomationProvider.
Set the list of controls who implement the IToggleProvider to be Button, ListItem, MenuItem, and TreeItem under certain conditions. To get more information on the conditions visit the page for the individual UIA control types.

For additional reference, see implementation of another provider on Fabric: #11874
