That is Microsoft's ToggleSwitch component. It's a standard component, so I was just going with something that's built into the UWP framework. See this: https://docs.microsoft.com/en-us/windows...ns/toggles

Microsoft uses that same component in the Windows 10 settings. Go into the settings in Windows 10, go to something like "Display" and you'll see that same component used in the same way there.

Understood. And probably why I hate Windows 10's settings dialogs! Seems everyone wants to be an iPhone.
