This should work with a Basic4ppc Form and Panel but not with a FormEx. It returns the internal module and control name where the "." is replaced by an underscore and is prefixed by one (IDE/legacy compiled) or two (optimised compiled) underscores.
B4X: 
obj.FromControl("Button1")
obj.Value = obj.GetProperty("Parent")
obj.Value = obj.GetProperty("propName")

yes,if parent of control is FormEx it's return CSenchancedForm(((
and getcontrols() not work with FormEx.
Agraham maybe you add this metod to FormEx?

I cannot as a library control does not know its Basic4ppc name. However every control has a Tag property for programmer use so you could set all the Panel and Forms and FormEx Tag properties to their Basic4ppc names and use that to identify the parent.

B4X: 
   obj.FromControl("Form1")
   obj.SetProperty("Tag", "Form1")
   obj.Value = obj.GetProperty("Tag")
   Msgbox(obj.Value)

   obj.Value = FormEx1.ControlRef
   obj.SetProperty("Tag", "FormEx1")
   obj.Value = obj.GetProperty("Tag")
   Msgbox(obj.Value)
