You can access the current Frame from a Controller via its Controller.Frame property. Using the retrieved Frame, you can access all Controllers created for the current Frame via the Frame.Controllers property. You can also access the View displayed by the Frame via the Frame.View property. To access the control representing a Frame in a UI, use the Frame.Template property.
