Hi Paweł;

  Unfortunately no. :-(

  That is because the DC & the DS controls are not aligned in the System Class hierarchy.Thus no related inheritance between the two.  :-(

You can see this in the PB IDE's  object browser ...

FWIW: What I do in my STD Framework for common code implementation is to use a Global Function & pass a "PowerObject" Object Pointer. Then cast that POP in the GF to the correct object class based on using a TypeOf() command introspection.  HTH

Hi Paweł,

I believe a straight cast is not possible, because both objects are inherently different types (even if they share a common interface). However, I think it's possible to convert from one to the other manually, please see this previous community forum post on the matter: https://community.appeon.com/index.php/qna/q-a/how-to-have-a-single-function-works-on-both-a-datawindow-and-a-datastore
