Is there something like :
function GetControlOf(var _a:TPersistent):TControl;
where _a is either a property or a sub-property ?

No. TPersistent does not have any link available to the containing control,
if there is even such a control used in the first place. So there is no way
for the RTL to implement such a function. Individual TPersistent
descendant classes must manually expose their own properties for that kind
of link.

I stored the TControl if any in a base class inherited from TPersistent...
